Why Does My Tooth Hurt When I Bite Down?

Pain when you bite down is your tooth trying to tell you something. The most common causes range from cracked teeth to infection, and knowing when to call the dentist is important.

Pain on biting is one of the most meaningful symptoms in dentistry. Unlike fleeting sensitivity to cold water or sweets, pressure pain usually points to a specific, physical problem, and most of the causes do not get better on their own.

Every person in the office is so personable. That first off makes you comfortable. But then the methods used to clean my teeth, particularly. I don't feel a thing, and it's the first time in my life that I haven't. And I have a lot of anxiety about dental work, and I really do not feel a thing when my teeth are being cleaned
Response from the owner:Thank you for your kind words! We’re so glad our team could help make your experience comfortable and relaxing. It means so much to know you felt at ease with your care!
I came here with my 18 year old daughter who has an immense fear of Doctors and Dentist , The kindness and understanding without any judgement we received from Dr.Thom was just unbelievable. The work he did on my daughter was life changing for her . I would recommend him to anyone . Just amazing, kind talented Doctor.
Response from the owner:Thank you so much for your heartfelt words! It means a great deal to our team to know that you felt welcomed, understood, and cared for. We’re especially grateful you shared how meaningful your experience was.

We met Dr. Shawn in Sept 2023 and in December, he removed our adult nonverbal son's wisdom teeth. Not gonna hold you, general anesthesia is billed incrementally (by the minute/quarter-hour) and is a heavy financial investment. I love this clinic because it really is a safe space for special needs families. There's a huge calm that accompanies knowing your dependent person is getting healthy. Dr. Shawn is exceptional. We drove 6 hours to get here so we'll choose a local practice for routine sedation cleanings down the road. I hope to see more neurodivergent acceptance built locally in our state's dentistry like this team has here. Meanwhile we are so grateful for this practice and grateful our son was in Dr. Shawn's care.
Response from the owner:Thank you so much for sharing your heartfelt words. We’re honored to be a place where families feel safe, supported, and understood. Your trust in Dr. Thoms and our team truly means so much to us.

The dental anesthesia center is hands down the best dental office I have ever been to. I neglected my teeth for years due to severe dental anxiety. I had work done under anesthesia with doctor hoffman who did an amazing job. Doctor Behl is not only a fantastic dentist but one of the nicest people I have ever met. The dental hygienists are both thorough and gentle. Stop your search and just go here
Response from the owner:Thank you for your incredibly kind words! We’re so glad our team could help make your experience comfortable and positive. We truly appreciate your trust and recommendation!

Dr. Behl! I cannot recommend Dr. Maris Behl enough. If you have dental anxiety, she is truly the kind of dentist you hope to find. If teeth could be wrapped in pillows and protected by flying unicorns, Dr. Behl would somehow make it happen. I have significant anxiety around dental procedures and have needed deeper sedation for dental work in the past. From the beginning, Dr. Behl took the time to listen to my concerns and made me feel genuinely heard rather than dismissed or rushed. She created such a sense of trust and safety that I was eventually able to have my dental work done with only nitrous instead of full sedation, which is something I honestly didn’t think I would be comfortable doing. During my crown placement, she explained what she was doing throughout the procedure, which made an enormous difference in keeping me calm. She also took the time to address a filling that had been bothering me for what felt like forever — and she actually fixed the problem. What stands out most about Dr. Behl is how safe I feel in her care. She is compassionate, patient, communicative, and incredibly attentive to how her patients are feeling. For someone with dental anxiety, that combination is invaluable. Finding a dentist I trust this much has completely changed my experience with dental care. I am incredibly grateful to Dr. Behl and would recommend her without hesitation, especially to anyone who has dental anxiety or has struggled to feel comfortable receiving dental treatment.
Response from the owner:Thank you for such incredibly kind words! We’ll be sure to pass this along to Dr. Behl. We’re pretty sure the flying unicorns are going to be the part she remembers most! 🦄💙 We’re so glad our team could help make your experience a more comfortable one.

1. A High Bite

Sometimes the cause is mechanical and simple. If you recently had a filling or crown placed, and that exact tooth now hurts when your teeth come together, the new restoration may be sitting slightly too high. Even a fraction of a millimeter is enough to make one tooth absorb more force than it should, and it becomes sore and sensitive to pressure.

This is one of the easiest problems in dentistry to fix. A quick adjustment to the restoration usually resolves the pain within days. If a recently treated tooth hurts when you bite, call your dentist; do not wait for it to settle.

2. A Cavity That Has Reached the Deeper Tooth

Small cavities are often painless. By the time a tooth hurts under chewing pressure, decay may have worked through the enamel into the dentin, the softer layer underneath, or close to the nerve at the center of the tooth. Pain that shows up when food presses into a specific spot, especially with sensitivity to sweets, often fits this picture.

Caught at this stage, the tooth can often be repaired with a filling or crown. Left alone, decay keeps advancing toward the nerve, and the next stop is usually much worse pain and more involved treatment.

3. A Cracked or Fractured Tooth

A distinctive pattern to watch for: sharp pain when you bite down, or more classically, a sharp jolt when you release the bite. Cracked teeth can be maddening because the pain comes and goes, often only hits at certain angles, and the crack itself may be invisible on an X-ray.

Cracks happen from chewing ice or hard foods, from nighttime grinding and clenching, from large old fillings that leave the remaining tooth walls thin, and sometimes from an unlucky bite on a popcorn kernel. Treatment depends on how deep the crack runs: a crown that holds the tooth together, a root canal if the crack reaches the nerve, or extraction if it runs below the gumline. The earlier a crack is found, the more options you have.

4. An Abscess or Infection at the Root

If the tooth feels “taller” than its neighbors, throbs on its own, and hurts intensely when you bite or even tap it, infection at the root tip is a strong possibility. Pressure pain happens because infection creates swelling in the bone around the root, so the tooth literally has less room.

Other signs may include swelling of the gum or face, a pimple-like bump on the gum, a bad taste, or fever. An abscessed tooth is not a wait-and-see situation. Dental infections can spread, and the pain tends to escalate quickly. Call promptly, and if you develop facial swelling, fever, or any difficulty swallowing or breathing, seek emergency care immediately.

5. Gum Disease or a Jaw Problem

Teeth are not fused to the jaw; each one sits in a socket cushioned by a ligament. Gum disease that has damaged the supporting bone can leave a tooth slightly loose and tender under pressure. Similarly, a blow to the tooth, or even a period of heavy clenching and grinding, can bruise that ligament and make biting sore for a while. Your dentist can tell these apart with an exam and X-rays.

When to Call the Dentist

With bite pain, the safest rule is simple: if it lasts more than a day or two, is severe, or comes with swelling or fever, call. Pressure pain almost never fixes itself, and every cause on this list is easier to treat early.

If fear, a bad past experience, or a severe gag reflex is what is really keeping you from making that call, you are exactly who our practice was built for. At The Dental Anesthesia Center, diagnosis and treatment can be completed comfortably under sedation or general anesthesia, and extensive treatment can often be finished in a single visit.

Contact The Dental Anesthesia Center

A tooth that hurts when you bite deserves attention now, not someday. Call The Dental Anesthesia Center in St. Louis at (314) 862-7844 or request a consultation online. We will find the cause and help you fix it, comfortably.
