Natural teeth have a tendency to get darker as we get older. There are several more or less effective over-the-counter tooth whitening products and toothpastes available in drug stores and pharmacies that may be helpful in making your teeth lighter again. The most effective and safest way, however, is to do this under the supervision of a dental professional, who can assess the reason for the darkening and select the most appropriate solution.

The teeth may be discolored with “external” stains from tea, coffee, tobacco, red wine etc., which can only be removed with special cleaning and polishing instruments, preferably by a dentist or dental hygienist. If that’s the case, this cleaning should be done before any other tooth whitening procedure.

Depending on the severity of the tooth discoloration, the dental professional may select from several whitening options, which are done either directly in the office or at home. For home tooth whitening, a “mold” (bleaching tray) is typically custom fabricated to fit over your teeth, then filled with the whitening material and worn at home as instructed. There are some possible side effects with this, especially teeth becoming temporarily more sensitive (another reason to do this under supervision from a dental health care provider).

In your question, you mention that “some” of your teeth are getting darker. The whitening procedures mentioned above are only helpful for teeth that are mostly intact and without large fillings, crowns, or other restorations. Some of the filling materials may get darker over time, while others do not change at all. In general, they cannot be “bleached” or “whitened” like natural teeth and may need to be replaced. In addition, any tooth decay must be removed prior to starting any whitening procedure. It would be advisable to consult with a dentist to ensure the best results are achieved.
