Whitening your teeth under the supervision of the dentist is the safest method of teeth whitening. Your gumline and lips are protected against the effects of bleach through the use of rubber and gauze seals. As well, the dentist will monitor you throughout your teeth whitening treatment.
Alternative methods of whitening such as over-the-counter whitening kits can be less effective as they use reduced amounts of bleach. Furthermore, trays that are not customised for your mouth can cause bleach to leach onto the gumline. When bleach is exposed to oral tissue for long periods of time it can cause adverse effects such as chemical burns.
To begin your teeth whitening treatment, the dentist will protect your gums, cheeks, tongue and lips by using a rubber appliance as well as gauze seals. This prevents the bleach solution from moving away from your teeth and onto sensitive areas such as the gumline.
Next, they will paint whitening gel onto the tooth surface. A UV light is used to heat the solution which activates it to penetrate deeper into the enamel. In general, this process can take between 60 to 90 minutes.
Once treatment is completed, you will be able to see results instantly.
