Who Doesn’t Teeth Whitening Work For?

Teeth whitening is a fast, painless way of removing stains from your teeth, but it does not always work. That can be frustrating for a person who has invested their time, hope and money into the procedure.

If you were to have your teeth whitened only to get underwhelming results, you would ask yourself many questions about the effectiveness of your dentist. Keep reading to find out why teeth whitening sometimes produces lackluster results.

How traditional teeth whitening works

Teeth whitening is a cosmetic treatment used to remove stains and discoloration from otherwise healthy teeth. It works by applying a bleaching agent to the teeth. The most popular teeth whitening compounds are peroxide-based.

When done at the dentist's office, teeth whitening occurs in the following way:

  • The dentist makes an impression of the patient's teeth
  • The impression serves to make a custom-made tray that will fit over the teeth
  • The dentist protects the gums by covering them with a rubber shield or gel
  • The dentist puts a whitening product into the tray and fits the tray onto the teeth
  • The bleaching agent acts on the enamel to remove stains and discoloration

The bleaching agent sits on the teeth for about 30 minutes per session. The entire process happens three more times over the course of four weeks. A dentist may use more intense teeth whitening procedures when regular teeth whitening does not get the job done. Deep bleaching is one of these alternatives.

When does teeth whitening fail?

There are some situations which cannot be resolved with regular teeth bleaching and sometimes, teeth whitening just will not cut it. Teeth whitening is unlikely to work for teeth with the following problems:

Discoloration from tooth decay

A dentist will not even whiten the teeth before treating decay and any other dental problems.

Discoloration on tooth restorations

Teeth whitening products are meant to act on enamel, not porcelain, resin or any other material used to make restorations. Using bleaching agents on restored teeth will have no effect.

Intrinsic stains

Regular teeth whitening works on surface stains. Unfortunately, some people have stains that run deep into the enamel. Examples are tetracycline staining and dental fluorosis. Micro-abrasion or deep bleaching techniques can remove these stains.

Teeth whitening may also fail if you use a less-than-perfect DIY treatment. If you choose to whiten on your own, the bleach may be distributed unevenly. This could be a result of an over the counter teeth tray that fits imperfectly or whitening strips that peel off.

Uneven teeth whitening could also happen when accumulated plaque and tartar block the bleaching agent from reaching the underlying teeth. That is why a dental professional should clean the teeth before you receive whitening.

Alternatives to teeth whitening

Dental bonding, veneers and dental crowns can cover discolored teeth. These teeth restoration methods have cosmetic purposes as well, and unlike teeth bleaching, they last many years.

Let your dentist guide you

Trial and error is not a good strategy when it comes to improving your smile. Before starting any cosmetic dental treatments, consult a skilled and experienced dentist. They will examine your teeth, and based on your unique situation, they will advise you on the best way to deal with stained teeth.
