Black coffee, tea and red wine are best avoided if people want to keep their teeth white.

Anyone who does not want to visit the dentist for tooth whitening treatments may want to take advice from one news provider on foods to try and stay away from.

The Hindustan Times reports that many drinks can lead to yellow, stained teeth and it is best to try and avoid them where possible.

For example, red wine creates rough spots that not only discolours them, but also causes stains to become deeper.

Similarly, black coffee is also described as a “deadly staining agent” and mild cups that have been diluted with milk can be much better.

The same applies to tea, while drinking through a straw could help to lessen any discolouration.

“Dark sodas, including diet, are harmful to teeth because of their sugar and phosphoric acid content,” the publication adds.

Some other top tips to keep teeth sparkling are to brush them twice a day and drink eight glasses of water every 24 hours, Irwin Smigel, creator of Supersmile, recently wrote on the Daily Beauty Reporter blog from Allure.

People wanting to get their teeth whitened should see a dentist.

People looking for the best teeth whitening treatments would be well advised to have a dental professional carry out the procedure, it has been claimed.

ClickPress reported the importance of a bright, welcoming smile cannot be underestimated, as it can boost confidence and make a person more attractive.

As a result, more people are now using take-home teeth whitening kits and while these are unlikely to damage the teeth – if used correctly – Brits could achieve better results by having a professional handle their smile upkeep.

Indeed, people are advised to research the treatment ahead of having it carried out and one of the best ways to do this is online.

Elsewhere, The Smile Company recently announced it has set up teeth whitening clinics in both Manchester and Birmingham airports.

The firm has set up a clinic in the passenger lounge of the airport and will provide laser teeth whitening treatments to travellers hoping to boost the brightness of their smile.

A teeth whitening centre has been set up at a UK airport.

People heading off on their holidays or getting back to the UK after a trip abroad can now have their teeth whitened at Birmingham airport.

The Smile Company has set up a clinic in the passenger lounge of the airport and will provide laser teeth whitening treatments to travellers hoping to boost the brightness of their smile.

Patients can book online in advance of their journey and the 20-minute laser teeth whitening treatment can be carried out while they are waiting to board their plane.

In addition to offering laser teeth whitening services, the clinic will also sell take-home teeth whitening kits to help people gain whiter teeth.

Elsewhere, KVAL News recently reported that Dr Dan Vodvarka, a practicing dental health professional in the US, has claimed people worried about the safety of take-home teeth whitening kits should rest easy, safe in the knowledge that as long as they are used correctly, they should be fine.

A Conservative candidate had her teeth whitened in a poster campaign.

A Conservative candidate hoping to win a seat in the upcoming General Election has come under fire after a billboard image of her was apparently digitally enhanced.

Caroline Dinenage hopes to take over from Sir Peter Viggers after the peer announced he would be standing dowen following the revelation that he used taxpayers’ money to fund a floating duck house in his back garden.

The poster in question was erected on a billboard on the A32 and in it, Ms Dinenage appeared to have been airbrushed and had her teeth straightened and digitally whitened.

Ms Dinenage’s personal assistant Glenn Duggan told the Telegraph: “You can see that it’s been touched up but Caroline had no knowledge of this. She is very surprised.”

Elsewhere, WorlDental recently reported Laser teeth whitening treatments differ greatly in cost depending on where people have the treatment carried out, but the results can often be worth the investment.

Jessica Simpson’s pearly white teeth are not as carefully kept as they may appear.

Hollywood actress Jessica Simpson has made quite a disturbing confession that she does not brush her teeth.

The A-list celebrity and star of films such as Dukes of Hazzard and Blonde Ambition claimed she only ever uses mouthwash and fights plaque by using her jumper to wipe her teeth!

Emergency dentists might therefore be forgiven for being stunned by her pearly whites and would no doubt recommend that this is not a course of action that should be followed to maintain good oral health.

Elsewhere, Fiji Village recently reported ensuring teeth are brushed daily is key to helping teeth stay healthy and a person’s smile remains bright.

Dental officer Dr Maher Angez told the publication a failure of many young people to brush twice a day and the increased consumption of sugary snacks has meant oral health in general has declined in recent years.

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.

The pearly-white smiles of this year’s X Factor finalists are all thanks to dental veneers and tooth whitening treatments, it has been revealed.

Writing for the Guardian, Deborah Orr claims that "you have to laugh" at the fact that all of this year’s X Factor contestants have been treated to emergency dentistry in order to brighten their on-screen grins.

She reveals that she initially did not realise that they had been given tooth whitening treatments and dental veneers ahead of the live shows.

As a result, on watching the first weeks of the finals, she adds that the eye-catching smiles on show were more attention-grabbing than some of the controversy that has made headlines in the press.

However, it is not only the contestants for whom emergency dentistry has been on the cards.

Days ago, it was revealed that Simon Cowell has been encouraging fellow judge and mentor Louis Walsh to consider teeth whitening in order to look his best for viewers of the high-definition broadcasts of the show.

Tooth whitening is the way one woman goes about improving her appearance.

Jill from Whitby responded to a recent Teletext question about how she would amend her appearance if she could and said while cosmetic surgery is out of the question, perfecting her smile is not.

She does not think she has the courage for a nip and tuck – so tooth whitening is her only indulgence.

And Jill was not the only person to mention cosmetic dentistry as something they are interested in.

The Teletext discussion also included Doncaster resident Marie’s comments. She said her "once nice smile" is fading away and therefore she would change her teeth if possible.

Last week, the Baltimore Sun advised readers on certain ways to stop their dental features ageing them.

Tooth whitening was recommended for brightening up a smile and keeping it shiny and "gleaming".

Veneers were also highlighted as an option, although a consultation with the dentist was suggested to find out more.
