Even with proper dental care, your teeth can discolour with time. If your teeth are in good condition but do not look as white as they used to be, a cosmetic dentist in London can help you restore the shine to your teeth. Teeth whitening is a fast and effective cosmetic procedure designed to lighten your teeth without removing your enamel. It cannot provide a radical colour change, but it can help improve your existing tooth colour.
Types of Teeth Whitening Treatments
There are two main types of whitening procedures: vital whitening, for teeth that have live nerves, and non-vital whitening, for teeth that have had root canal treatment and no longer have live nerves.
Vital Teeth Whitening
Vital teeth whitening is the most common type of tooth whitening. It uses a hydrogen peroxide gel that is applied directly to your tooth surface. A laser activates the gel and allows whitening to happen faster.
Non-Vital Teeth Whitening
Vital whitening may not lighten teeth that have had root canal treatment because the stains come from the inside of the teeth. Non-vital whitening is a procedure that whitens teeth from the inside. It involves placing a whitening agent inside the teeth and putting temporary fillings over the top. The teeth are then left for several days, until they reach the desired shade.
Side Effects of Teeth Whitening
Teeth whitening is a safe and effective form of cosmetic dentistry, although it can cause some side effects. You may find that your teeth become more sensitive to cold foods and drinks for a short while following treatment. You may also experience gum discomfort, a sore throat or white patches on your gum line. These side effects are usually temporary and normally disappear within a few days.
Longevity of Teeth Whitening Effects
Teeth whitening is not a permanent solution. However, with good oral hygiene and regular preventive care, its effects can last for up to three years. You can improve the longevity of the results of your treatment by avoiding foods and drinks that can stain your teeth. Stopping smoking can also help prevent staining.
