Reasons Why Your Teeth Hurt When Eating Sweets

But why exactly do your teeth hurt when you eat sweets? Knowing more never hurt anyone. Therefore, know the causes of tooth pain upon contact with sugary substances below:

Enamel Loss

Sugary snacks and drinks have fermentable carbohydrates, which boost the harmful bacteria in your mouth and produce acid. If the acid is not rinsed away, it can lead to enamel erosion. This is because the acid removes minerals from your tooth enamel. Enamel loss makes your teeth more susceptible to sensitivity and decay. Hence, enamel loss can be the cause of your toothache when eating sweets.vans invierno Peluca vulcana pendientes candela de reina anfra rodamientos gorras y pañuelos under armour mariposas de agradecimiento baratas panera exterior vertical tostadora hitachi vans invierno panera exterior vertical usb wifi smart tv samsung adidas y3 yohji run black de donde son las alpargatas adidas y3 yohji run black nike air versitilw 3 black gold talla 40

Salivary flow is vital for replacing the mineral loss in the enamel. However, frequent snacking can prevent saliva from replacing minerals that your tooth enamel needs.

Improper and aggressive brushing can also cause your tooth enamel to wear away. Thus, practicing good oral hygiene with limited sugary snack intake can help lessen tooth sensitivity.


The sugary snacks do more than enamel erosion. The sugar in the snacks reacts with the bacteria in your mouth to form a sticky film called plaque. Plaque rests on the surface of your teeth and under your gums, demineralizing your tooth enamel. Once plaque successfully wears away your tooth enamel, bacteria and acid are free to invade your teeth and get to the dentin layer.

Then, the tooth decay progresses to forming holes in your teeth, known as cavities. Cavities need to be immediately filled by a dentist; otherwise, they can worsen with time. When sugar, bacteria, and other stimuli enter the cavity, you feel a sudden, sharp pain. Usually, one feels tooth sensitivity to warm, sugary, and cold substances. Cavities are a common reason our teeth hurt when eating sweets.

Gum Disease

Plaque, when left untreated, can harden into tartar. As a result, your gums get irritated. You might also experience these in your gums:

  • Inflammation
  • Infection
  • Bleeding
  • Swelling

Swollen and sore gums can heighten tooth sensitivity due to the exposed nerve endings of your teeth. Your gums start to recede, increasing tooth pain when you eat sweets.

How To Stop Tooth Pain When Eating Sugar?

If your teeth hurt after you eat sweets, you should visit your dentist. Your dentist can fill the cavity. Moreover, in case of gum disease, deep teeth cleaning might help. Following good oral hygiene like brushing and flossing regularly can aid in stopping tooth and gum problems. And not to forget: reduce your sugar intake!
