Dentist Lawrence Neville reveals foods you should avoid if you want a perfect smile

Some of your favorite foods could be ruining your smile, and it’s not just red wine and coffee you should watch out for, according to the leading cosmetic dentist.

The Doctor. Lawrence Neville, dentist and owner of Spa Dental in Sydney’s CBD, told FEMAIL that green tea, white wine and even fruit can ruin your smile.

The dentist explains that while teeth appear smooth on the surface, the enamel is actually covered in microscopic depressions and that is why they become stained.

Dr Lawrence Neville, dentist and owner of Spa Dental in Sydney’s CBD, told FEMAIL that green tea, white wine and even fruit can ruin your smile.

“This uneven surface has a tendency to catch and hold food and drinks that cause stains to get into the mouth,” he said.

‘Certain foods and drinks with a high acid content can also damage enamel, enlarging depressions so stains penetrate deeper.’

Drinks can be particularly harmful with green tea, one of the worst when it comes to darkening your smile.

“Tannins are one of the substances that are notorious for staining tooth enamel, especially when consumed multiple times a day,” he said.

‘According to studies, the color of your tea will also determine the color of the coloring. Surprisingly, green tea has the highest levels of tannins and excessive consumption can cause gray spots.

‘While black tea has the least coloring impact and will produce a more yellowish hue.’

Fruit juice is highly acidic which means it is very harmful if consumed regularly and will cause your teeth to become stained.

Foods to eat for a whiter smile:

Cauliflower, especially when crispy, as it promotes saliva development

Apples

strawberries

celery

Cheese

Foods to avoid for a whiter smile:

Fruit juice

Green tea

Red and white wine

Cooking sauces with tomato, turmeric or beetroot

Red and purple fruits

“Fruit juice does not stain the enamel, but it weakens the enamel and increases the likelihood of stains from other substances,” he explained.

‘Resist the urge to brush immediately after drinking fruit juice; this will exacerbate the damage to the enamel tubules which are already weakened by the acid contained in the juice.’

And your choice of drink is just as important to consider at night, he explained, with red and white wine ultimately detrimental to their pearly whites.

“If you’re enjoying an alcoholic beverage, my advice is to avoid darker liquids,” he said.

This should be done “as long as you can” after whitening treatments, he added.

“If you think of ingredients that stain your hands or clothes when you’re cooking, those foods will also stain your tooth enamel,” he said.

‘Swap red wines and dark acid mixers like coke, for a glass of white wine or even a vodka soda.’

“That said, high-acid beverages such as white wine and prosecco can weaken and damage enamel, creating pockets in the enamel that allow other liquids to penetrate further into tooth tissue.”

Cooking sauces can also cause heavy stains, especially those that contain turmeric, beets, and tomatoes.

“If you think of ingredients that stain your hands or clothes when you’re cooking, those foods will also stain your tooth enamel,” he said.

Glossy fruits can also stain your teeth, and while your dentist will recognize that they are great for your overall health, they should be consumed with caution.

“Berries such as blueberries, blackberries and strawberries are also rich in pigmentation and contribute to the coloring of the glaze,” he said.

The dentist also listed foods that can help improve your smile with strawberries, despite their dark color, appearing at the top of the list.

“They are packed with an enzyme known as malic acid, which naturally makes teeth whiter,” he explained.

Foods that require a lot of chewing, like cauliflower, apples and carrots are also good, he explained, because they promote saliva, which is a great natural cleanser.

Cheese and celery also made the list of the best foods to eat, with the doctor acknowledging the benefits for both teeth and gum health.

Dr. Lawrence said that regular professional cleanings can limit the risk of stains in the long run.

“If you can’t resist regularly consuming these foods and drinks, make sure you drink water afterwards, and in the case of high-tannin drinks, try brushing your teeth,” he said.
