Teeth Whitening Treatment: Few Facts You Should Consider
Teeth whitening is one of the most popular cosmetic dental procedures all over the world. It removes stain and discolouration from the teeth, making them appear healthy and beautiful. According to the norms in the UK, only a dentist is allowed to perform this cosmetic dentistry treatment. That apart, a dental hygienist or dental therapist can also perform it but only on the prescription of the former.
It’s important to remember that whitening is never a one-time therapy. Teeth whitening professionals confirm that you need to undergo the treatment from time to time to maintain the shine and the whiteness on the teeth.
The reason behind teeth staining
The outer, hard layer of the teeth is called the enamel. This enamel layer, affected by a number of different factors, catches up stain. These are summed up as following:
- Excessive consumption of tobacco in any form
- Heavy intake of beverages like coffee, red wine and even tea
- Not maintaining proper oral hygiene
Even old age is another major cause that affects the natural whiteness of the teeth. These factors cause the teeth to stain on the outer surface. You may also have intrinsic stains, which is mainly caused by excessive exposure of the teeth enamel to fluoride. This factor usually shapes up when one is young and the teeth are just erupting.
Certain medications, like tetracycline base antibiotics, are another powerful agent that discolour your teeth. This factor is in fact so strong that if a to-be mother takes this medicine during the second half of her pregnancy, it stains the child’s teeth. Thus, cosmetic dentistry experts associated with a renowned teeth whitening treatment clinic in London suggest patients to avoid over-the-counter medicines.
However, teeth whitening, as a therapy, proves effective on the stains that occur on the teeth surface or the extrinsic strains.
The result of teeth whitening is affected by other oral health issues that you may have. For example:
- If you’ve receding or decayed gums, whitening can make your teeth sensitive.
- Caries or cavities in the tooth have to be filled up before availing the cosmetic dentistry treatment of teeth whitening. Else, there’s always the chance that the whitening chemicals can get into the inner, soft and more sensitive dentin layer of the teeth.
- If you’ve receded gums, the exposed teeth roots may appear discoloured inspite of undergoing a successful teeth whitening therapy.
- The whitening treatment doesn’t work on veneers and crowns.
Whitening procedure types
The treatment procedure can broadly be categorised in two parts:
- The vital whitening procedure is done on the teeth with living nerves.
- On the other hand, non-vital whitening is strongly recommended by smile dentist clinics on your tooth that has undergone root canal treatment before and has no live nerve.
Teeth whitening like other cosmetic dentistry treatments isn’t usually covered by insurances. Whereas, preventive dentistry treatment of teeth cleaning is widely covered by those policies. Hence, you should undergo teeth cleaning first and only after that if you still feel like going for more, then avail the cosmetic dentistry therapy.
