What type of tooth stains has the best prognosis for removal?
Extrinsic stains have the best prognosis for removal. They occur on the surface of the teeth, caused mainly by dark colored beverages, foods, tobacco, or just general wear and tear over the years. These are generally minor and can be easily removed. If extrinsic stains are left untreated, they can gradually move into the dentin and become fixed.
Some patients may notice yellow or greenish color around their gums. This is primarily due to improper oral care. Therefore, by maintaining good dental hygiene, discoloration of teeth can usually be avoided. You may also want to avoid drinking excess coffee or tea, or drink them with a straw since pigments in certain food and beverages can also darken teeth. Smoking is yet another common cause of teeth discoloration.
If your teeth have been stained by sodas, coffee, tea, smoking, or just general aging, you are likely to be a good candidate for teeth bleaching. Moreover, because fillings and crowns do not respond to bleaching, patients with natural or non-restored teeth are likely to have wonderful response to bleaching. Yellow stains respond better than brownish stains. Grey teeth are the least responsive to bleaching.
Wearing metal braces can also result in tooth discoloration because constant contact of metals with dental plaque produces surface stains. Iron deficiency can also discolor your teeth. Iron deficiency usually causes black stains on the surface of your teeth. Depending on the severity of each case, your dentist may recommend a certain mouthwash, gel, or liquid to lighten darker stains.
Although the teeth whitening procedure is an excellent way to brighten your dull teeth, you must consult a qualified dentist. Patients with gum or tooth sensitivity as well as patients with receding gums are usually advised to exercise caution with whitening procedures as it could have adverse effects on them. On the other hand, if your dentist sees that you are an ideal candidate for teeth whitening, as most are, you may choose to proceed with the treatment with minimal concern.Back to Teeth Whitening Page
