A glass of bubbling prosecco may add sparkle to your celebrations, but it doesn't always do the same for your teeth. While sipping this festive favourite brings a touch of glamour to Christmas parties, it can have a less-than-dazzling effect on your smile.

What is a prosecco smile?

Prosecco, an Italian sparkling wine, has become a go-to favourite in recent decades, often celebrated as a widely-available, cheaper alternative to its upscale cousin, Champagne. It's also known for its distinctive flavour - a blend of sweet-tasting bubbles balanced by a fresh, acidic bite.

However, Dr Sahil Patel, Cosmetic Dentist and Founder of Marylebone Smile Clinic warns that while prosecco is often associated with the joy and sparkle of carefree celebrations, some dental issues can arise from regular indulgence in this popular drink.

The acid content and high levels of sugar in prosecco are problematic for your teeth. This can lead to dental decay, particularly affecting the front teeth - the ones most visible when you smile.

"Among dentists, it has been reported anecdotally that dental decay affecting your front teeth spikes during the festive season," Patel explains. "Decay is seldom present in the front teeth, due to us being able to access them easily for cleaning and fluoride exposure.

"Prosecco can create a situation where decay affects your front teeth, possibly requiring fillings and other dental work later on in the new year - hence the term 'prosecco smile.'"

How does alcohol affect teeth?

Patel warns that regular alcohol consumption can have significant long-term consequences on tooth enamel, gums, and overall oral health.

Enamel erosion

Even in moderation, regular alcohol consumption subjects your teeth to acidic and sugary substances - especially in wine, beer, and cocktails.

"Acid in particular can erode tooth enamel over time," says Patel. "This constant exposure may increase tooth sensitivity and vulnerability to cavities."

Dry mouth

A healthy amount of saliva is essential for neutralising acids and protecting teeth from decay and infection.

Patel explains that because alcohol dehydrates your body, it can cause your mouth to become dry, therefore reducing the amount of saliva it produces.

"The more alcohol drunk in one sitting, the more pronounced the negative effects on oral health," says Patel. "High volumes of alcohol increase dehydration, exacerbate dry mouth, and create an acidic environment that can lead to rapid enamel erosion."

Discolouration

Alcoholic drinks like red wine and cocktails can contribute to plaque build-up and staining, leading to yellowing or browning of the teeth.

Gum disease and tooth decay

A lack of healthy saliva production allows harmful bacteria to thrive, leading to plaque build-up.

Patel warns that this is especially true when you're drinking alcohol with sugary mixers. These can negatively impact your gums - causing inflammation and disease, as well as tooth cavities and even tooth loss.

Bad breath and health conditions

Long-term heavy drinking contributes to bad breath due to dry mouth and bacterial growth. It also raises your chance of developing oral cancers.

Is all alcohol bad for teeth and gums?

According to Patel, the type of alcohol you consume has varying levels of impact on your dental health - mainly due to differences in acidity, content and sugar levels.

He describes the following beverages as being particularly harmful to your teeth:

  • Wine - both red and white wines are highly acidic, which can erode tooth enamel over time. Red wine may also stain teeth due to its tannin and chromogen content, while white wine - although less likely to stain - still has a high acid content that could contribute to enamel erosion.

  • Spirits - for example, vodka, whiskey, rum - spirits generally have a higher alcohol content, and can be more dehydrating than other types of alcohol. This can lead to dry mouth, reducing saliva flow. Many spirits are consumed with sugary mixers, which increases plaque build-up and the likelihood of cavities.

  • Beer - beer is usually less acidic than wine, but often contains higher levels of sugar, particularly in sweeter varieties or craft beers. This sugar can support the growth of harmful bacteria, leading to plaque build-up, cavities, leaving you susceptible to gum disease. Beer also contains compounds that may cause staining, though less so than red wine.

How to avoid a prosecco smile

Sticking to 14 units of alcohol a week is a safer bet for your overall health. But to keep your teeth happy too, Patel recommends these simple tips.

Switch it up

Alternating your alcoholic drinks with water helps rinse away acids and sugars from inside your mouth. This can reduce their negative effect on tooth enamel.

Patel says: "This also helps keep your mouth hydrated, promoting saliva production, which neutralises acids and protects your teeth."

Sip through a straw

Drinking alcoholic beverages like prosecco through a straw can help minimise contact with your teeth.

Patel says: "This reduces the harmful effects of enamel erosion and staining, and is particularly useful for acidic drinks like wine and cocktails."

Don't rush to brush

After drinking acidic beverages like prosecco or wine, wait at least 30 minutes before brushing your teeth.

Patel says: "Acid temporarily softens tooth enamel, and brushing your teeth right away can lead to enamel wear. Instead, rinse your mouth with water or chew sugar-free gum to stimulate saliva production.

"Brush your teeth twice a day with fluoride toothpaste, and floss regularly to remove plaque and prevent build-up."

Go easy on the booze

Less frequent, moderate alcohol consumption helps shield your teeth from harmful effects.

Patel says: "If possible, opt for drinks with lower acidity, such as light beers or spirits mixed with non-acidic mixers."

Check in with your dentist

Regular visits to the dentist help catch any early signs of enamel erosion, gum disease, or cavities.

Patel says: "Your dentist can provide professional cleanings to remove tartar and advise on ways to protect your teeth from alcohol-related damage."

Chomp some gum

Chewing sugar-free gum stimulates saliva production. This helps neutralise acids in your mouth and safeguard your teeth.

Patel says: "It can also help freshen your breath and reduce the chance of plaque build-up after drinking."

Cut the sugar

If you’re drinking cocktails, try to avoid sugary mixers that can contribute to plaque and tooth decay.

Patel says: "Opt for drinks with fewer sugars, or mix them with soda water or non-acidic options. If you want to enjoy a festive tipple, I recommend drinking a clear liquor which is less acidic and contains less sugars which in turn, will cause less damage to your teeth."
