Cosmetic dentistry could help to boost an individual's self-confidence, as can maintaining good oral hygiene.
Professor Damien Walmsley, scientific adviser to the British Dental Association, said that keeping your mouth healthy is important for simple functions, like eating.
However, it also helps to "boost self-confidence", he explained.
"It's important to brush your teeth with fluoride toothpaste at least twice a day, restrict your intake of sugary and acidic food and drink and visit your dentist regularly," Professor Walmsley advised.
The comments follow research from Mintel, which suggested that oral health is becoming increasingly important with Brits.
Indeed, the survey found that sales of oral hygiene products have risen by 14 per cent over the past five years to stand at £833 million in 2010.
Mouthwash was found to be the fastest growing sector in the oral hygiene market, with sales increasing by 44 per cent.
Meanwhile, the results of the latest NHS Information Centre survey found that 26 per cent of adults have opted for a certain type of dental treatment because of cost factors.
