People could look younger with a brighter smile.

People could attempt to hold back the years by investing in teeth whitening treatments, according to the Times.

Dr Uchenna Okoye, clinical director of London Smiling, told the newspaper that having a brighter smile can help people improve their confidence and feel better about themselves and this is something that teeth whitening can help to achieve.

She argued that there is a “notion that terrible teeth denote a shining soul, while perfect pearls mean vanity, subterfuge and something that is suspiciously Yank”.

However, this should not hold people back from having the treatment carried out.

Elsewhere, Dr William Greenberg at Skin Thera P Medical Cosmetic & Laser Spa in New York recently claimed that anyone wishing to look younger might like to have some Botox injections or dermal filler to plump up their skin and remove any wrinkles.

Indeed, Dr Williams noted that the treatments are continually growing in popularity, with many dentists now offering Botox in their surgeries.
