Teeth whitening is one of the most sought after dental cosmetic procedures and it has something to do with how society perceives a white, luminous smile to be beautiful. If you’re not so confident with your smile, a simple and short teeth whitening procedure can instantly remedy that. But before you call up your dentist and sign up for a teeth whitening procedure, here are some of the things which you ought to know:

1. Not all whitening kits work the same way.

If you’re thinking that the at-home whitening kit which you bought in some pharmacy will miraculously give you white teeth after just one night, then you might be in for a rude awakening. While in-office whitening procedures can give you noticeable results in just a couple of minutes, this isn’t the case with at-home whitening kits. This is because the two have different levels of their active ingredient. While the active ingredient, hydrogen peroxide, may be the same, their concentrations differ. For instance, at-home whitening kits contain lower amounts of the active ingredient while the gels that dentists work with have very high levels of peroxide. Peroxide can extrude out the stains but it can also damage the enamel. While your dentist might be qualified enough to work with peroxide, you aren’t as skilled as he or she is. So for your protection, you are only allowed to handle minute amounts of hydrogen peroxide.

2. Teeth whitening may not be effective for interior stains.

When the stain is concentrated within the dentin layer, then you might have a difficult time whitening your teeth using the custom whitening procedures. This is because hydrogen peroxide only works on the enamel. At the same time, when the peroxide effectively dissolves the enamel, this damage is already irreversible and you’ll be end up with teeth that are susceptible to infection and sensitivity. An easy way to whiten a tooth which has interior stains is to cover it up with a dental veneer or a crown.

3. Cavities and teeth sensitivity should be checked and corrected before pushing through with the procedure.

When you have cavities or any breaks on the enamel region, this could trigger pain and discomfort during the whitening procedure because the active ingredient seeps into the inner dentin layer. In order to prevent that from happening, you should have cavities filled in to prevent the peroxide from penetrating into the tooth.
