Tooth pain can be unsettling, especially when it happens while you're chewing or biting down. There could be several reasons why your tooth hurts when chewing. This article will help explain common causes of tooth pain when biting down and what you can do to alleviate it.
Tooth pain can occur for a variety of reasons, from simple sensitivity to more serious dental issues. Below are some of the most common causes:
One of the most common reasons you have a toothache when biting down is tooth sensitivity. This can happen when the tooth enamel wears away, exposing the dentin, a sensitive part of the tooth. When pressure is applied, such as during chewing, it can trigger a sharp pain.
Tooth sensitivity often occurs due to receding gums, gum disease, or worn-down enamel. If teeth hurt when chewing, especially when eating hot or cold foods, tooth sensitivity is likely the culprit.

Cavities are another common reason your tooth hurts when putting pressure on it. When decay penetrates through the enamel and into the inner layers of the tooth, it can lead to toothache pain when biting down. The pressure from chewing can aggravate the nerve, causing discomfort.
Cavities that are left untreated can worsen and lead to more severe problems like infections, so it’s important to visit a dentist if you're experiencing pain.

If you're experiencing sharp tooth pain when chewing, you might have a cracked or damaged tooth. Cracks are often too small to see, but when you bite down, the pressure can cause the crack to shift, irritating the tooth’s nerves and leading to pain.
Cracks can happen for various reasons, such as teeth grinding or chewing hard foods. If only one tooth hurts when biting down, a crack could be to blame.

A loose filling or crown can also cause tooth pain when biting down. When a filling or crown becomes loose, it exposes the inner layers of the tooth to pressure, cold, and heat. This can result in a toothache when you chew or even cause the tooth to feel sore to the touch.

Advanced gum disease, also known as periodontal disease, can cause pain and sensitivity in the teeth, especially when biting down. When gums recede or become infected, they expose more of the tooth’s root, leading to discomfort.
Another related cause is a dental abscess, which is an infection at the root of a tooth or in the space between the gum and tooth. Dental abscess is often the reason for molar pain, as the infection puts pressure on surrounding tissues.

Teeth grinding, or bruxism, is a common cause of teeth hurting when biting down. This condition can wear down your teeth, cause cracks, and damage the enamel. If you experience a sore tooth when biting down in the morning, grinding your teeth at night could be the cause.
Teeth grinding puts excessive pressure on the teeth and jaw, leading to soreness, especially in the molars.

If your teeth are not properly aligned, you might notice molar pain when biting down. An uneven bite can cause certain teeth to endure more pressure than others, leading to soreness or pain when you bite.
This type of pain is common in patients who have recently had braces adjusted or are dealing with bite alignment issues.

Molars are essential for chewing and grinding food, so it’s common to experience molar pain when chewing. Molars endure more pressure than other teeth, so they are more susceptible to issues like cracks, cavities, and grinding damage.
If you're asking why your molars hurt when biting down, it’s likely related to one of the causes listed above, such as tooth decay, a damaged tooth, or gum disease.
When dealing with teeth hurting when biting down, it’s essential to visit your dentist for an accurate diagnosis. Depending on the cause, your dentist might recommend one of the following treatments:
In the meantime, over-the-counter counter pain relievers can help manage your pain, and avoiding hard or crunchy foods will reduce pressure on the affected tooth.

If you're dealing with tooth pain when biting down, it's crucial to identify the underlying cause. Whether it's tooth sensitivity, a cracked tooth, or gum disease, addressing the problem early can prevent more serious dental issues down the road.
If you’re experiencing pain in your back tooth when biting down, or if your tooth hurts when putting pressure on it, consult your dentist to explore the right treatment options for your dental health.
