How To Rehydrate Teeth After Whitening

After you get your teeth whitened, they can become dehydrated. This is unhealthy and can make your teeth absorb color from foods, ruining whatever improvement your whitening treatment did.

However, there are ways to rehydrate your teeth fast, and you can avoid certain foods until they are rehydrated. Dehydration usually happens after in-office dental treatments. While getting your teeth treated at the dentist rather than at home is more effective, it is also more likely to dehydrate your teeth.

Why Do Teeth Get Stained and Dehydrated?

Contrary to what you might think, your teeth can absorb liquids. Coffee, tea, wine, and many other fluids can penetrate below the surface of your enamel. Your teeth can absorb liquids like a sponge; this both makes staining possible and allows whitening treatments to work.

Like your skin, your teeth have pores. Hydrogen peroxide is a common whitening ingredient not only because it can remove stains but because it can help widen the pores.

The peroxide opens the pores, breaks down the stains by a chemical reaction, and flows out again, leaving your teeth whiter. However, this dehydrates your teeth. Tooth dehydration is not limited to the surface – the inside of the tooth can become dehydrated, which can cause problems.

The peroxide raises the temperature inside your tooth, which dries it out. Peroxide also causes water to flow out of your teeth by opening the pores.

While your teeth are dehydrated, they will absorb liquid like a dry sponge, making your teeth particularly vulnerable to staining. Drinking coffee, red wine, or anything else that can cause stains shortly after whitening is a bad idea.

Dehydration can also make your teeth way too sensitive. Normally, your teeth can protect their nerves from drastic changes in temperature. However, dehydration makes the nerves more vulnerable, so a cold drink can cause pain.

How Long Does it Take for Your Teeth to Rehydrate?

It takes two days to a week for your teeth to fully rehydrate on their own after any kind of dehydrating dental treatment. You need to be very careful for at least a day or two after your whitening treatment, as you can immediately re-strain your teeth.

How to Rehydrate Teeth After Whitening

The simplest way is to drink enough water. You don’t have to drink a huge amount of it every day, but stay hydrated. If you aren’t drinking enough, you will produce less saliva, and your teeth won’t rehydrate for a long time. Your teeth also get vitamins and minerals through your saliva.

Again, drinking really a lot of water doesn’t work. Drinking enough to stay hydrated works; drinking much more than that won’t help. Sloshing water against your teeth won’t work either and might prevent your teeth from getting rehydrated.

Simply keeping your mouth full of saliva is the best way to rehydrate your teeth. There is no special trick to it – just don’t do anything that dries your mouth out. Smoking, intense exercise, sweating a lot, not drinking enough, and drinking anything that dehydrates you will dry out your mouth.

Tooth dehydration sometimes occurs for reasons other than whitening treatments. If you become dehydrated while you are asleep, you might wake up with lighter-colored spots on your teeth. These spots are there because some parts of your teeth are dehydrated. Chronic tooth dehydration can lead to cavities.

Drinking enough water is good for your health in many ways. The human body is made mostly of water, and you need a lot of it every day for your body to work properly.

Many people are frequently dehydrated because they drink sugar, caffeine, and alcohol, which dehydrate them. Don’t have a soft drink when you’re thirsty – drink water instead.
