Sugar sensitivity is one of the main reasons why your teeth hurt from sweet foods. It is different from other types of sensitivity that is caused by extreme temperatures.

Sugar sensitivity is a typical teeth problem that can be caused by one of the following reasons.

Loss of enamel

If the teeth begin to lose their enamel, they can become more sensitive, not just to sweets, but to other things as well. i.e. extremely cold or hot drinks or food.

Enamel is the front/outer layer of your teeth that protects them from cavities and decay. But when it starts to erode, it gives a sign of a risk for tooth decay.

So when the enamel is damaged, it exposes the teeth’s sensitive inner layer and causes the teeth to hurt.

If the outer layer of teeth enamel is damaged, your teeth become sensitive to sugary foods, hot or cold drinks, and even irritants have easier access to your teeth’ nerve center, which can cause extreme pain.

Here are a few reasons that can cause loss to your teeth enamel!

Wrong brushing technique

Brushing with an improper technique can affect your teeth enamel.

If you brush too hard or your brush’s bristles are tough, that can also damage your enamel.

If you are sensitive to sweets, avoid using a toothbrush with stiff bristles and use a brush that has soft bristles.

Brush your teeth gently in a round/circular motion. Don’t press hard or straight back on the teeth or gums.

Cleaning your teeth using a proper technique can remove all the particles from there without hurting your enamel.

Choose a manual or electric toothbrush, but always make sure you are brushing slowly, and making circular motions with the brush because that’s the only right way!

Eating acidic food

Foods and drinks that touch your teeth can affect your enamel!

Besides, items like red wine, coffee, soda, and acidic drinks can also do some damage to your teeth.

Such foods can erode the enamel, leading your teeth with a risk for cavities.

What’s more, these foods can also cause stains in your teeth.

Dental Caries/Cavities

Sugary foods can cause cavities.

The bacteria that cause cavities stuck on your teeth and overgrow.

Cavities can cause pain and infect your inner tooth.

Not only artificial sugar drinks, but fruit juice can also lead to caries development, however sometimes people ignore how it impacts their oral health.

Tooth damage

Any trauma to your teeth can cause sensitivity.

If damaged by a car accident or while playing sports, a tooth can become sensitive to cold, hot, and sugary foods.

Grinding your teeth can also harm your teeth by wearing down the enamel, causing increased sensitivity.

Tooth whitening treatments

If you are experiencing sensitivity after using a whitening treatment, then it is likely that the product is the culprit behind the problem.

That is, some patients often report tooth discomfort after at-home or professional tooth whitening treatment.

However, the pain caused by whitening treatment is usually temporary.

If it persists for more than two days, contact your dentist who performed the whitening treatment.

Gum disease

Gum diseases can significantly affect your oral health.

That is, it can also make your teeth sensitive to hot, cold, and sweet foods.

Gum diseases like gingivitis and periodontist are usually responsible for giving you pain from sweets in your teeth and gums.

Gapped teeth

Teeth that have unwanted gaps allow food to stuck in themselves, making it easy for the sugary items to stick into your teeth and gums and cause sensitivity.

Such teeth should be kept clean after taking any food to avoid pain after taking hot and sweet foods.

Teeth scaling

You can also feel some sensitivity after teeth scalping and root planing.

The dentist removes all calculus deposits (tartar) and plaque from the teeth below your gum-line in scaling.

That process can cause a slight discomfort around your teeth for some days, which in return might make your teeth sensitive to sweet, hot and cold foods for up to four to six weeks.

However, sensitivity after scaling is normal for everyone, so you shouldn’t consider it a severe problem for your oral health.

Overuse of sugary items

Foods and drinks with high sugar are one of the significant reasons behind teeth sensitivity.

You should avoid over intake of sweets and maintain proper hygiene to prevent their adverse effects.

What’s more, if your teeth are decayed or having any infection, then the sweet foods can not only make them sensitive but also destroy them dramatically.

Poor diet or Poor eating habits

Improper diet or poor eating habits can also be a reason for teeth pain.

For example, Vitamin C is essential against teeth sensitivity prevention and needed for oral health in general.

Thus, if you are not taking the ideal amount of Vitamin C, you could suffer from several oral health problems, including tooth decay.

How can I prevent tooth pain/sensitivity to sweets?

Teeth sensitivity can be prevented by maintaining good oral health. Here are some of the essential points that can help you ease teeth pain from sugary foods.
