Teeth Whitening

What is bleaching?

Bleaching or whitening the teeth is a popular cosmetic dentistry procedure that helps patients with discolored or darkened teeth to have whiter, brighter smiles. Beaching is a process of lightening the teeth and can be done at home or in the dentist's office. The procedure dates back to the 1980s and became increasingly popular in the 1990s. Bleaching uses peroxide that is applied to the teeth for a period of time. There are many different types of peroxide on the market, and one of the most commonly used is a gel. It is important for a patient to be diagnosed by a dentist who can determine if bleaching is recommended.

Is bleaching effective?

Bleaching takes some elements of the proteins out of the enamel and whitens the teeth. In most cases, bleaching generates good results. Individuals with yellowish teeth will have better results than patients whose teeth are gray or blue in color. Bleaching is not for everyone. For example, it won't work on individuals with porcelain fillings or crowns because bleaching isn't effective on man-made products. In this situation, the natural teeth will lighten and not blend with the existing fillings or crowns.

Why do teeth become discolored?

Teeth may become discolored as a result of poor hygiene, use of tobacco, hereditary factors, systemic diseases, medications and substances found in coffee or tea. Those who grind the teeth may also have discolored teeth. The color of teeth along the gumline is often yellow and dark, but lighter along the edge. Individuals who grind their teeth wear away the lighter edge -- leaving the darker portion of the tooth. Some medications may also discolor teeth or produce white spots on the enamel.

What types of bleaching methods are available?

There are two bleaching systems available for consumers. They include power bleaching, which is done by the dentist in the office, and the home bleaching system, which the patient does on his or her own at home.

In either case, a Dentist must supervise the process. If bleaching is recommended, the dentist and patient must decide which system would work the best. Some dentists take photos prior to bleaching and use a shade guide to determine the desired color.

Here is a look at both methods:

Power bleaching is a procedure that is done in one office visit and it takes one to three hours. The teeth are bleached in one session using a high concentration of peroxide. The dentist will apply a rubber dam or wax to the gums to protect them. The bleaching substance is applied to the teeth and a strong light may be used to accelerate the process. This system is for the patient who wants immediate results and doesn't want to do it at home. Higher concentrations of peroxide are used for this method and may cause sensitivity to the teeth. If this happens, the dentist may opt to slow down the bleaching process or use a fluoride solution to reduce sensitivity.

Home bleaching is a procedure that a patient does at home, primarily at night. The dentist makes special trays that fit over the teeth to hold the solution on the teeth. The patient puts peroxide in the special trays and wears them for up to eight hours at a time. Most of the lightening occurs during the first two hours, but the bleaching process continues as long as the patient wears the trays. The entire process may take from two to six weeks. A dentist should monitor the process once a week. The disadvantages of this system is that it takes longer and the patients has to be disciplined to do it at home.

Are over-the-counter bleaching products effective?

The Australian dental Association recommends that individuals who opt to alter the color of their teeth via bleaching consult a dentist.Over-the-counter bleaching systems may not be safe and there is potential for damage because of the lack of supervision. Toothpastes with whiteners are not effective because they do not contain a high enough level of chemicals to make any difference. Tooth polishes have abrasives in them that are not good for the teeth.

How long will the whitening effect last?

The treatment results depend on the original shade of your teeth.

The effect usually lasts for one to three years but can last longer depending on the diet. Then you may need to top up.After whitening treatment which normally take 1 hour We supply you with a free” introductory kit of maintenance” including “custom tray”, “home whitening gel”, “desensitizing gel“ at no cost to you, then therefore it guarantees the effect of whitening.To Some people find that their teeth are extra sensitive several days after the treatment has been completed but it usually wears off after some time.

we currently charge $750 for this service including free “ home bleach kit’ and free assessment .

We are happy to introduce the Zoom! Advanced Power (Zoom 3) Whitening System - only a few practices in Australia are offering this revolutionary technology. Extensive research and clinical studies indicate that whitening teeth under the supervision of a dentist is safe. In fact many dentists consider whitening the safest cosmetic dental procedure available. A clinical study performed by Loma Linda University on the effect of whitening gel on tooth enamel, confirmed that Zoom! is safe. The study concluded that Zoom! "does not adversely affect the microhardness and surface morphology of human enamel." A clinical study was conducted by Discus Dental to evaluate the efficacy of the Zoom! system. Fifty subjects participated in a study that showed that the average shade change with the Zoom! system is 8 shades and that the Zoom! system is "safe and effective for whitening teeth rapidly." In addition, minimal sensitivity was noted during the study, with a significant number of patients reporting no sensitivity

Why do people get veneers?

Veneers cover the front surface of your teeth, masking imperfections in your smile.

This includes discolorations brought on by root canal treatment and drug stains (like from tetracycline) and misshapen teeth, made so by wear over time, naturally-occurring craters or bulges, injury or other natural causes. Veneers can also be used to close gaps between teeth or mask misalignments.

Patients should consult with a dentist before making any decisions regarding veneers. Veneers are permanent, so an informed decision is of the utmost importance. Bonding and crowns are common alternatives to veneers that patients might want to discuss with their dentist.

Can anyone get veneers?

Veneers are not the right choice for everyone. Your teeth must be healthy to receive veneers, free of decay and active periodontal disease. Patients whose teeth are weakened due to decay, fractures or large fillings may not be able to hold a veneer. Patients who clench or grind their teeth – actions which can chip or crack veneers - may also want to consider other treatments.

What are veneers made of?

Veneers can be made of porcelain or from resin composite materials. Each has benefits, and patients are encouraged to discuss their options with a dentist in order to make the best choice. In general, porcelain veneers are better at resisting stains and reflecting light to mimic properties in your real teeth. Resin composite veneers are thinner and require the dentists to remove less of your real tooth surface for placement. Both types of veneers are custom-made in colors to match your teeth and keep your smile looking natural.

What is the procedure for getting veneers?

After an initial consultation with the dentist who will be placing your veneers, the dentist will remove a very thin layer of enamel from the surface of your teeth and make a mold of your teeth.

A lab will use this model of your mouth to fabricate your veneers. The dentist may place temporary veneers on your teeth while you wait for the lab make your permanent veneers.

When you return to the dentist's office, your dentist will spend time examining the color and fit of the veneers before he puts them on your teeth. The dentist may need to trim or reshape the veneers to get a better fit or shape for your mouth before permanently affixing them. When everything is just right, the dentists will clean, polish and score your teeth to make the cement adhere better. The veneer will be applied, and a blue curing light might be used to help the cement bond more quickly. A third visit may be required for the dentist to check on how the veneers fit and to see how your gums are responding to the new veneers.

How do you care for veneers once they are placed?

Patients who have veneers should care for them the same way they care for their natural teeth: by brushing and flossing regularly, and visiting the dentist for regular check-ups.

Even though porcelain veneers resist stains, your dentist may recommend that you avoid staining foods, such as coffee, tea and red wine.

Veneers can last for five to 10 years before they need replacing, but patients need to see a dentist when the veneer cracks or breaks. Because tooth enamel is removed to prepare the tooth for a veneer, a broken veneer leaves the underlying tooth exposed for further damage. Dentists recommend patients not bite their nail or chew on hard objects like ice and pencils to minimize damage to the veneers.

What are the advantages of dental veneers?

Veneers offer the following advantages:

  • They provide a natural tooth appearance.
  • Gum tissue tolerates porcelain well.
  • Porcelain veneers are stain resistant.
  • The color of a porcelain veneer can be selected such that it makes dark teeth appear whiter.

Veneers offer a conservative approach to changing a tooth's color and shape-veneers generally don't require the extensive shaping prior to the procedure that crowns do, yet offer a stronger, more esthetic alternative to bonding.

> back to top

What are the disadvantages of dental veneers?

There are some disadvantages and risks associated with veneers. Because your tooth enamel has been removed, your tooth may become more sensitive to hot and cold foods and drinks.

Also, teeth with veneers can still decay. When this happens, patients may need a crown to cover the entire tooth.

Veneers are also costly, and often cannot be repaired when they chip or break.

Amalgam: Myths vs. Facts

The following information from the American Dental Association corrects much of the misinformation about silver-colored fillings known as amalgam.

Myth: Dental amalgam causes numerous health problems.

Fact: Not true. You should feel very secure that the many organizations responsible for protecting the public's health have said time and time again that amalgam fillings are safe. Those organizations include the World Health Organization, United States Public Health Service, the National Institutes of Health and the Food and Drug Administration.

> back to top

Myth: There are better materials for treating cavities, but the ADA continues to promote use of dental amalgam because it receives money from amalgam manufacturers through its Seal of Acceptance program.

Fact: Be assured that the ADA does not profit from amalgam, nor does it promote the material.

The cost of maintaining the ADA Seal program is financed primarily through ADA member dentist dues.

What the ADA does promote is having patients make informed decisions about their dental care in consultation with their dentist. The choice of a particular filling material is determined in partnership by the dentist and patient, and based upon a variety of considerations, including size and location of the cavity, patient history, cosmetic concerns and cost.

> back to top

Myth: The ADA justifies amalgam use by saying the filling has been around for 150 years.

Fact: When making treatment recommendations, dentists rely on the best-available science and their own clinical experience. Because amalgam has been around so long, the dental profession and scientific community have learned a great deal about its durability, reliability and safety. Just like aspirin, amalgam has withstood the test of time and is still a valued option for patients.

Myth: Removal of amalgam cures some diseases.

Fact: It is unconscionable to lead people to believe that their serious illnesses may improve by undergoing unnecessary dental treatment.

In fact, leading medical experts and health organizations have negated such statements and conclusions.

For example: "There is no scientific evidence to connect the development of MS or other neurological diseases with dental fillings containing mercury." (National Multiple Sclerosis Society)

"According to the best available scientific evidence there is no relationship between silver dental fillings and Alzheimer's." (Alzheimer's Association) "There is no scientific evidence of any measurable clinical toxic effects [of dental amalgam]." (American Academy of Pediatrics)

> back to top

Myth: Dental amalgam fillings release mercury vapors that are harmful to the body.

Fact: Minute amounts of mercury vapor (between 1-3 micrograms* per day) may be released from amalgam under the pressure of chewing or grinding, but there is no scientific evidence that such low-level exposure is harmful.

In fact, dental materials experts say one would have to have almost 500 amalgam fillings to even see the subtlest symptoms in the most sensitive person.

* 1 microgram is equal to 35.2 billionths of an ounce.

Myth: Dentists cannot tell their patients that amalgam contains mercury.

Fact: Actually, the ADA encourages dentists to discuss the full range of filling options with their patients so together they can decide what is the most appropriate treatment.

Dentures are artificial, removable replacements for natural teeth when disease, injury or years of inadequate dental care has left you with few or no healthy teeth of your own. Dentures, made to look like your natural teeth in shape and color, can replace all or some of your teeth. They are one option to restore your smile and reinstate your ability to chew food.

Why do people get dentures?

Replacing missing teeth has many benefits, both physical and emotional.

Teeth are vital for chewing, and good nutrition is vital to whole body wellness. The space left by missing teeth allows remaining teeth to shift, and out-of-position teeth can cause tissue damage in your mouth. In addition, teeth that have shifted and are crooked are difficult to clean, making tooth decay and gum disease bigger threats.

Without support from teeth, facial muscles will sag.

Teeth also help you to speak more normally, a vital part of your self image. It may take some practice at first, but speaking normally will get easier over time.

Are dentures an inevitable part of the aging process?

Not all senior citizens have dentures. Regular dental care (including daily brushing and flossing and regular trips to the dentist) enables many people to keep their natural teeth as long as they live.

Dental decay and gum disease, two effects of poor dental hygiene, cause many people to loose their natural teeth.

But decay and gum disease are not the only reason that people lose their natural teeth. Teeth can be damaged by xerostomia (dry mouth), diabetes, illnesses that make self care difficult (like Alzheimer's disease and arthritis), and drug therapies for other illnesses. Patients should talk to their dentists about any medications they take regularly and for prolonged periods of time.

What are the different kinds of dentures?

There are three types of dentures available to patients. Each is appropriate for different situations.

  1. Complete dentures are for patients who have no remaining teeth on the top or bottom of their months. They include artificial teeth and gums which rest on the patient's natural gums.
  2. Partial dentures are for patients who have some natural teeth still in tact. They provide some artificial teeth and gums, connected by metal clasps that attach to your natural teeth.
  3. Overdentures are exactly what they sound like – artificial teeth that fit over your natural teeth when only a few natural teeth remain. This gives the dentures added stability. The dentist may have to reshape your natural teeth to fit the denture

How do dentures fit into your mouth?

There are two ways a dentist can fit dentures into your mouth:

  1. Conventional dentures are fitted at least two months after your teeth have been removed. The dentists will make an impression of your mouth so that the dentures can be made to fit onto your gums. There are no temporary dentures, however, so you will be toothless for a while between when your teeth are removed and when your dentures are made.
  2. Immediate dentures can be fit at the same time as your natural teeth are removed. Your dentist will make molds of your jaw weeks before removing your teeth, so that a dental lab can fabricate your dentures. Then, the same day that you teeth are removed, the dentists will fit your new dentures into your mouth. However, your jaw and gums will shrink after your natural teeth are removed; follow-up appointments will be necessary so that the dentist can adjust your dentures.

Attempting to adjust your dentures yourself can result in serious (and costly) damage to the piece. Ill-fitting dentures cause irritation, sores, and pain.

What care is required for dentures?

Like teeth, dentures should be cleaned daily. Use a brush made for cleaning dentures or a soft-bristled toothbrush. Use mild, non-abrasive cleaning agents, such as hand soap or dish soap.

Some toothpastes may even be too abrasive for use on your dentures; ask your dentist if you are unsure.

Even if dentures have replaced all of your teeth, you must still care for your mouth. Brush your gums, tongue and the roof of your mouth before inserting your dentures daily to remove plaque and other bacteria.

Discuss with the dentist how often you should visit the office for professional cleanings continued maintenance of your dentures.

Are there any alternatives for dentures?

Bridges and implants can substitute for dentures. Consult with your dentist to find which in the best remedy for your situation.

Root canal treatment

What does treatment involve?

Treatment often involves from one to three visits. During treatment, your general dentist or endodontist (a dentist who specializes in problems of the pulp) removes the diseased pulp.

The pulp chamber and root canal(s) of the tooth are then cleaned and sealed.Here's how your tooth is saved through treatment:

  1. First, an opening is made through the crown of the tooth.
  2. An opening is made through the crown of the tooth into the pulp chamber.
  3. The pulp is then removed. The root canal(s) is cleaned and shaped to a form that can be filled.
  4. The pulp is removed, and the root canals are cleaned, enlarged and shaped.
  5. Medications may be put in the pulp chamber and root canal(s) to help get rid of germs and prevent infection.
  6. A temporary filling will be placed in the crown opening to protect the tooth between dental visits. Your dentist may leave the tooth open for a few days to drain. You might also be given medicine to help control infection that may have spread beyond the tooth.
  7. The pulp chamber and root canals are filled and sealed.
  8. The temporary filling is removed and the pulp chamber and root canal(s) are cleaned and filled.
  9. In the final step, a gold or porcelain crown is usually placed over the tooth. If an endodontist performs the treatment, he or she will recommend that you return to your family dentist for this final step.
  10. The crown of the tooth is then restored.

How long will the restored tooth last?

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums. However, regular checkups are necessary. As long as the root(s) of a treated tooth are nourished by the tissues around it.
