Why Does My Teeth Hurt When I Bite Down

Exercise Daily – Wondering why does my teeth hurt when I bite down? If so, then read this guide to know every possible reason.

An indication that anything is wrong is when you feel pain in a tooth when you bite down or touch it. Pain relief and addressing any underlying issues may also necessitate medical attention.

When you bite down or put pressure on your teeth, does it hurt? You’ll benefit from this guide if that’s the case.

When you eat, your teeth may pain due to a variety of causes. In order to save your tooth, it’s important to know what causes a toothache and what you can do about it.

It’s possible that one of the following is the source of your tooth pain when you chew or bite:

The Tooth or Filling Hits Harder

The necessity of your teeth to make direct contact with one another is known as occlusion. In other words, occlusion may be used to explain how your teeth fit together as you eat. 

The pressure exerted during biting should be uniformly distributed. This is the ideal situation. In other words, no one tooth or filling carries more strain than it should. This can only be done when your lower and upper teeth occlude appropriately.

Your teeth may hurt if your tooth or filling has been improperly occluded. Most patients detect discomfort in their teeth as soon as their dental procedure is over and the sedatives wear off. 

In addition, the opposing tooth is painful when a tooth is positioned higher than the others. This occurs as a result of the additional pressure the tooth puts on the other teeth when they come into contact. So, it can be the first reason why does my teeth hurt when I bite down.

A Tooth with a Large Cavity

No, I’m not talking about a bad toothache or sensitive teeth. When you eat certain foods, you may get a toothache. Tooth decay or a cavity may be the cause. Most people are susceptible to tooth sensitivity when they have a cavity. 

Additionally, it is possible to experience a persistent toothache after eating sugary foods. A common cause of toothache is the accumulation of food lodged in deep pits and crevices in the teeth.

The filling might potentially fall out if you apply excessive pressure to the region of the tooth. Because of this, your food will begin to accumulate in that place. When you bite down or contact it, this causes pain and sensitivity in your teeth.

As a result of extensive tooth decay, you’ll experience excruciating pain in your teeth every time you eat. It might also irritate the nerve of your tooth. 

However, not all of the cavities are so bad. When you bite down, you may notice an odd sensation or a rough edge that should prompt you to arrange an appointment with your dentist.

Tooth Abscess

A dental abscess is another possible cause. When you bite down, it might harm your teeth. Abscesses are painful collections of pus that are frequently the result of bacterial infection. 

Your tooth is under strain because of this fluid or swelling in your tooth or gum. As a result, it hurts when you chew on it or press on it in any way. It can be another reason why does my teeth hurt when I bite down.

When you have a tooth abscess, the pain you feel is frequently irregular. As a result, it is mutable. Occasionally, you’ll be in a terrible mood. 

It’s not always observed. Small, red bumps occur on your gums near the tooth that is infected. The puss that is leaking out of the region also has a salty flavor. 

A serious infection that spreads to your jaw and other regions of your body might develop if it is not treated in a timely manner. Root canal therapy, on the other hand, might alleviate the pain you feel when biting.

Broken Tooth

One of the most difficult diagnoses to make is that of a broken tooth. Cracked teeth often exhibit no symptoms other than pain when you bite down, which is more than half of the time. 

If you get pain in your teeth after eating, the first step is to identify the source of the pain. Visit one of your dentists if you haven’t already. 

They will use a special biting stick to see if you have a broken root. When you apply pressure to a certain area of the stick, it tells where the pain is coming from.

Dentists can also use dental x-rays to detect more serious fractures. Hairline fractures, on the other hand, are commonly missed. 

Special diagnostic techniques are performed to detect hairline fractures in teeth. It is critical to address a fractured tooth as soon as possible. If left untreated, germs may enter the gap and cause tooth decay if it isn’t filled.

Gingivitis or Gum Disease

When you bite down, your teeth may pain because of an underlying infection in your gums. Inadequate oral hygiene is a common cause of periodontal disease. 

When your teeth hurt, go to the dentist for a checkup. We’ll take a look at your teeth’s attachment levels at this time. 

Gum disease can cause tooth sensitivity and eventual tooth loss. It’s also possible to have bleeding, swollen gums, or exposed tooth roots as a result of tissue separation. 

Patients who have gum disease also experience tooth sensitivity, tartar accumulation, gaps between teeth, and tooth movement.

Wisdom Teeth Growing

Tooth pain when eating might also be brought on by an unnatural development of your wisdom teeth. Because wisdom teeth are the final set of teeth to erupt, they typically do so in an uncomfortable or insufficient place. 

Intense molar tooth discomfort, especially while chewing or biting, is the result of this condition. Wisdom teeth extraction is beneficial to most people. Third, molar extractions aren’t always required or safe. 

Consult your dentist if you’re having problems with your wisdom teeth. Your dentist can alleviate your toothache by providing the appropriate therapy for your specific situation. Ibuprofen can also be used in the meantime to alleviate discomfort in the teeth.

Pressure in the Sinuses or Congestion

Tooth pain may not always indicate a problem in the mouth. Because the roots of your teeth are so close to your nasal sinuses, an irritated sinus can cause tooth discomfort. Your premolars and molars are the most sensitive teeth in your mouth. 

That’s why your upper teeth hurt when your sinuses are inflamed. Sinusitis is frequently accompanied by back toothaches. It is important to see your dentist if you have any chronic pain in your back teeth.

Root Exposedness and Gum Recession

When you apply pressure to the exposed root of a tooth that has receded from the gum line, you may experience severe tooth sensitivity. 

The majority of patients report a sharp, throbbing pain in their teeth whether they’re eating or drinking. Your root surface has been clogged with food, resulting in this problem. 

Forceful tooth brushing, teeth grinding, gum disease, and trauma are just a few of the things that can lead to gum recession.

Even if you do all in your power to avoid it, trauma or damage can still occur. When it comes to saving your natural tooth, you should know what measures you should take.

Teeth Grinding and Clenching Habits

Teeth grinding and jaw clenching can put additional stress on your teeth. There is a risk of tooth soreness or breakage due to this. People who sleep with their teeth clenched may not even know they’re doing it.

It can be another reason why does my teeth hurt when I bite down.

Some people’s jaws tighten as a normal reaction to stress. Dentists, on the other hand, are well-versed in the art of calming their patients. You can keep your teeth healthy by using a mouthguard. 

The question is, how can I determine whether my teeth hurt when I bite down? In most cases, jaw pain caused by clenching or grinding teeth can be felt on one side of your face, if not the entire body. 

So, if a particular tooth is giving you discomfort, it’s possible that it’s not from a cavity.

When Your Mouth Hurts, Take Action Quickly.

When it comes to tooth pain, it’s not like other sorts of discomfort that just go away on their own. You can’t just relax more or use over-the-counter painkillers to fix it. 

There is an underlying dental problem that is causing your tooth pain. You shouldn’t ignore a toothache when you bite down.

Any time a person experiences dental discomfort, a trip to the dentist is a medical need. A dentist is able to execute the required operations to repair the tooth so that the patient is no longer suffering any discomfort in the mouth.

The longer you wait to see the dentist, the more likely it is that the dental pulp within your tooth will be damaged, which can be quite painful. If the pulp is damaged, an endodontist may be brought in to heal the tooth.

A tooth infection, sensitivity, a TMJ dysfunction, or any number of other disorders might be at blame for your discomfort. If you’re having problems with your teeth, you should make an appointment with your dentist right away.

Why does my tooth hurt when I bite down but no cavity?

However, you may have sensitive teeth if you experience this. When the dentin, the tooth’s innermost layer, is exposed, it causes sensitivity. It is possible to have a toothache like this even if there is no visible decay. When the enamel wears away, or the gums recede, the dentin is frequently revealed.

Do cavities hurt when you bite down?

When you bite down, you may feel a sharp pain and heightened sensitivity if you have a cavity or a crack. Long-term pain magnifies already-existing health problems. A cavity or fracture might allow germs to enter your tooth’s pulp if it is large enough and deep enough.

Do cavities hurt when you chew?

The enamel and dentin layers of the teeth might disintegrate as a result of tooth decay and dental cavities, resulting in sensitivity to chewing. There is a risk that food or germs might get inside the teeth and cause discomfort.
