Teeth whitening procedures vary both in price and effectiveness.

Teeth whitening services can vary in price, reports the Daily Herald.

According to the publication, not all teeth whitening procedures cost the same amount, or have equally good results.

However, it is not only price that can determine which procedure is most likely to be effective.

Individual characteristics can also have an effect, meaning an expert consultation is essential before deciding on which action to take to attempt to whiten teeth.

Depending on the reasons behind the discoloration of a person’s teeth, bleaching them back to bright white can have varying results.

People with fillings or veneers are also told to seek expert advice before bleaching their teeth, as only the natural enamel is likely to lighten in shade.

“What’s best for you depends on several things, including the type of discoloration and the amount of time and money you’re willing to spend,” the article explains.

Dental expert Dr Richard Hixson recently told Today’s THV that new technology is helping patients to have more control over the final shade of white that is achieved following tooth whitening procedures.
