It is a fact that people smile more when they know their smile reveals a mouth full of white, perfectly aligned teeth and healthy gums. It instils confidence and assists in positive daily interactions with friends, colleagues, acquaintances and family. On the other hand, discoloured and misaligned teeth discourage people from smiling and give a negative impression when meeting and communicating with others. Dental whitening can help solve this problem.
Dental whitening is a simple, affordable and effective procedure which whitens teeth painlessly. The end result is a sparkling white smile which is an instant confidence booster.
There are many reasons why our teeth discolour as we age. These can be divided into internal and external factors. With regard to external factors, coffee, tea and red wine are some of the major culprits. The tar and nicotine in tobacco cause teeth to yellow with time.
Internal discolouration problems include the natural process of aging, where the enamel on the outside of the tooth wears thin over time and the yellowish dentine inside the tooth begins to show through. A blow to the mouth may also cause discolouration as the body naturally produces more dentine to protect the tooth. Another factor which causes tooth discolouration is certain medications, such as antibiotics (tetracycline in particular), antipsychotics, some antihistamines and high blood pressure tablets.
It’s important to have a dental exam before embarking on dental whitening to ensure there are no contraindications so the best results are obtained. Patients should be over the age of 18 before having dental whitening and have paid a visit to the dental hygienist for a full dental cleaning. It is important to always maintain good oral hygiene to keep the teeth white and the gums healthy.
Dental whitening is not recommended for patients with periodontal disease, severe fluorosis, highly sensitive teeth or for pregnant or lactating women. Patients may experience some sensitivity after dental whitening but this is temporary.
