Image-conscious individuals contemplating teeth whitening procedures could be interested in recommendations from the British Dental Health Foundation (BDHF).
According to the organisation's chief executive Dr Nigel Carter, limiting the consumption of coloured food and drink could be a natural method of protecting smiles.
His comments emerge after the Scottish Daily Herald reported actor James McAvoy had succumbed to Hollywood pressure and received cosmetic dentistry.
The X-Men star reportedly decided to get his teeth whitened and straightened, despite previous claims he was unwilling to change his appearance for his job.
Dr Carter insisted that before opting for such procedures, it is vital that people adopt an at-home routine to ensure overall oral health is maintained.
He recommended the use of fluoride toothpaste in a bid to remove often unsightly stains caused by smoking, red wine or coffee.
"Whitening toothpaste may also help the effect last, once your teeth have been professionally whitened," he added.
