Teeth Whitening – Is It Safe?

Cosmetic dentistry is becoming increasingly popular and can include treatments to fit crowns, bridges, implants and veneers; all treatments which aim to improve the physical appearance of the teeth. One of the most basic and inexpensive forms of cosmetic dentistry is teeth whitening.

Cosmetic Dentistry Procedures

Nearly half of the population are unhappy with their teeth, the main reason for which is discolouration.[1]

Teeth Whitening

Teeth whitening is an easy and effective solution to this problem, but much like other forms of cosmetic dentistry, if performed incorrectly or inadequately the consequences can be rather uncomfortable.

DIY Teeth Whitening Kits

There has been a recent surge in popularity of home teeth whitening kits. This could be due to the ease of access of such remedies, or because of people’s reluctance to pay seemingly ever-increasing dental fees. However, these are often unsafe and/or ineffective. Some products may not declare all the precise chemicals present and this means that it is difficult to assess their safety, as a result burned gums, blistered lips or even more serious consequences may occur.[2]

Do DIY Kits Work?

Not only can home treatments be considered unsafe, but they may also be ineffective. Home teeth whitening kits must contain less than 0.1% hydrogen peroxide to be considered legal, however, Dental practitioners can legally use a 6% concentration of hydrogen peroxide, making it much more effective.[3]

Safest Method

The safest and most effective way to have teeth whitened is undoubtedly by having it done by a trained dental professional. It is illegal for anyone other than dentists or their teams to carry out teeth whitening.[4] If the dentist administers treatment incorrectly or inadequately and this ends up in personal injury occurring then dental malpractice may have occurred and you may be able to make a personal injury claim.
