Have you ever been enjoying a bite of food and noticed pain when you bit down, or an ache when drinking an icy beverage? You may have been experiencing signs of cracked tooth syndrome. Often, a microfracture in a tooth is too small to be seen to the naked eye and requires an x-ray to determine. There is a large range of symptoms and severity, which makes cracked tooth syndrome one of the trickier conditions to diagnose. There are many different causes and types of cracks that can occur in your teeth, so we’ll explore some of those, as well as what your treatment options are.

What causes Cracked Tooth Syndrome?

According to Medical News Today, cracked tooth syndrome can be caused by an injury to your mouth or biting down on an unexpected piece of hard food. However, it can also happen over time due to age. In addition to standard wear and tear, you can get cracks in teeth from grinding, or from abrupt changes in temperature such as drinking ice water after taking a mouthful of too-hot food. It’s important to note that this syndrome is common, and not due to a lack of proper oral hygiene or habits.

Is my tooth pain from a crack?

Tooth fissure pain may come and go depending on what movement or outside factor is triggering it, making it difficult to identify which tooth is suffering. If you suspect you’re suffering from cracked tooth syndrome, these are common symptoms:

  • Pain when chewing or “rebound pain” when you release the pressure from biting down
  • Sensitivity to extreme hot or cold temperatures, as well as sweetness
  • Erratic pain that only occurs when you’re aggravating the cracked tooth
  • Swelling of the gum around the cracked tooth
  • If it goes on too long, you’ll find the pain no longer comes and goes but hurts consistently

Can a cracked tooth cause jaw pain? Yes, some cracks affect the root of the tooth in the jaw. If you think you’re experiencing cracked tooth jaw pain see your dentist immediately.

What are the types of a cracked tooth?

There are many different types of cracks in teeth, but like most conditions, severity and treatment go hand-in-hand. If you know what to look for, you can catch it early for an easier fix. Cracks can appear or be identified as:

Craze lines–Show up as very small cracks in the outer enamel. The good news? While common in adult teeth, they cause no pain, are very shallow, and don’t require any treatment.

Fractured cusp–This kind of crack generally occurs around a dental filling causing minor pain. Your dentist can place a new filling or crown to protect the damaged tooth.

Oblique supragingival cracks–These only affect the crown and do not extend below the gumline. As a result, the teeth affected by these cracks are usually not painful.

Oblique subgingival cracks–These do extend below the gum line, and the teeth can be painful. Treatment, such as a root canal and crown may be necessary. It’s important to note that experiencing a cracked tooth after a root canal is possible since teeth that have undergone root canal treatment are weaker than normal teeth.

Oblique root cracks: The damage occurs below the gumline, most commonly in the jawbone. Tooth extraction is often the only treatment for this type of crack. Yet another reason to seek early treatment. Don’t ignore the pain, see your dentist as soon as possible.

Split tooth: Identified by a crack with distinct segments. An endodontist may be able to save a portion of the tooth depending on the position and extent of the crack.

Vertical root fracture: This is a crack that begins at the root and extends to the chewing surface. While this type doesn’t cause as much pain, they’re often diagnosed due to infection or tooth abscess in the surrounding bone and gum. An endodontist will determine the correct course of treatment.

How do I prevent cracked tooth syndrome?

You can’t fix cracks on your own, you can only try to prevent them. If you’re playing a contact sport or doing work where an injury could occur, make sure to wear a mouth guard or protective mask. You can still enjoy your favourite foods like popcorn or nuts, but be sure not to bite down hard. Cracked teeth from grinding during sleep or due to stress and anxiety, may call for wearing a night guard or mouth guard while you sleep.

Remember, the discomfort a cracked tooth may cause is a signal to you that you should seek help. Pay attention and don’t hesitate to make an appointment with your dentist
