Frequently Asked Questions about Cosmetic Dentistry

All permanent teeth are slightly off-white in color. Some teeth are darker, due to defects in tooth formation or from taking certain medication when young. These are intrinsic discoloration. Extrinsic discolorations, such as food and drink colors, can also be deposited on the surface of the teeth.

Professional teeth whitening can help in most situations. In general, off the shelf whitening toothpastes are not as effective as professional whitening but they are helpful in maintaining the color stability of your teeth after a professional whitening.

Crowns offer an overall coverage of teeth. Crowns are indicated when there is a need to strengthen teeth that are mechanically weakened (e.g. teeth with large cavities). Veneers, in general, refer to thin porcelain coverings that are bonded onto the exterior of the tooth. Good quality enamel, preferably intact enamel, is required for successful bonding.

Both crowns and veneers may be used for modifying colors or position of teeth.

Research for crowns has been done for a longer period of time while veneers are a relatively new procedure with less long-term scientific studies about them. The success rate for both is about 85% for the past ten years. This means that out of 100 crowns or veneers procedures done, about 15 of them need to be repaired or done again.

Weak or sensitive gums require gum treatment. Crowns or veneers cannot treat gum problems. It is advisable to consult a dentist to assess whether crowns or veneers are suitable for you and whether you need to address any existing gum problems.

Crowned teeth are no stronger or weaker than your own natural teeth. As a matter of fact, crowns are used for strengthening weakened teeth. With proper daily home care and regular professional maintenance (every 6 months check-up), crowned teeth will last for decades.

Teeth discolouration can be either external or internal. External and internal discolouration have different causes and their treatments are different. Smoking, as well as tea, coffee and soft drink consumption are some of the biggest causes of external staining. At times, irregularities on teeth surfaces may contribute significantly to the uptake of external stains too.

Intrinsic discolouration could be the result of a dead or infected tooth. External discoloration can be predictably treated with cleaning and whitening, while treatment for intrinsic discolouration will be more complicated. The key to effective treatment is to get a proper examination and diagnosis. Your dentist would be able to identify the causes of your concern and the relevant treatment.
