Whitening toothpastes : Tooth whitening is a procedure that brightens teeth and helps to remove stains and discolouration. Whitening is among the most popular cosmetic dental procedures because it can improve how your teeth look.
The outer layer of a tooth is called the enamel. Every day, a thin coat forms on the enamel and gathers stains. Tooth enamel have pores that add to stains. Whitening is not a one-time solution. It will need to be repeated from time to time Re-whitening can be done in the dentist's office or at home.
Home use whitening kits : For in-home whitening, your dentist will take impressions (measurements) of your teeth and will make one or two custom mouthpieces (trays) to fit you. The number will depend on whether you are having both upper and lower teeth whitened. It is important that the mouthpiece fit well. A close fit helps the whitening agent to remain in contact with your teeth instead of irritating your gums. Over-the-counter mouthpieces are unlikely to fit correctly. They can cause gum irritation if the whitening agent seeps out.
At home, fill each mouthpiece with a whitening gel your dentist provides. Wear the mouthpiece for several hours every day. Many people achieve the amount of whitening they want within a week or two. However, you may need to wear the mouthpiece for four weeks or longer.
Whitening is not a permanent solution. The stains will come back. If you smoke or consume staining foods or drinks, you may see the whiteness start to fade in as little as one month. If you avoid these sources of staining, you may not need another whitening treatment for six to 12 months.
You should discuss your whitening schedule with your dentist. You can talk about what whitening products would work best for you.
