Cracks in teeth can be a ‘ticking time bomb’ just waiting to catch you out at an inconvenient time. Cracks can be present for years and seem superficial and harmless but then suddenly give way and cause half of your tooth to fracture.

Cracks can propagate, like a crack in a windscreen, and can have devastating results. If a crack extends down on to the root surface of a tooth, usually the only option for the tooth is extraction.

Cracks can occur for a number of reasons

Large Fillings, Especially Amalgam

Cracks may develop when there are extensive fillings in the teeth, particularly those made of amalgam. The pressure and wear over time can lead to stress on the tooth structure, resulting in cracks.


Teeth grinding or clenching can exert excessive force on the teeth. This leads to the development of cracks. This repetitive pressure can weaken the tooth enamel and create fissures.

Biting on Hard Foods

Chewing on hard substances like nuts, ice, or hard candies can cause micro-fractures or more significant cracks in the teeth. This is especially true if the biting force is excessive.

Root Treated Teeth

Teeth that have undergone root canal treatment are more vulnerable to cracks due to the removal of the dental pulp, which can make them more brittle. It’s essential to be cautious and seek prompt attention if you experience any discomfort.


Traumatic events, such as accidents or injuries to the face, can result in cracked teeth. The impact from a fall, collision, or other accidents can cause visible or hidden cracks in the teeth.

Signs/symptoms of a cracked tooth

  • Short, sharp pain on biting (cracked tooth syndrome)
  • Deep pocket under gum line
  • Crack lines visible on tooth
  • Portion of filling/tooth fractured

How do I prevent cracks?

  • Limit bruxing/clenching of teeth
  • Limit crunching on hard foods
  • Strengthen teeth that have been root treated ie.placing a crown
  • Wear a custom mouthguard when playing sport

What to do if I do have a cracked tooth?

Cracks in teeth never heal. They sometimes stabilise but more often than not they progressively get worse over time. Reducing the stress on teeth can help preserve the crack or at least slow down the progression.

There are a number of options for cracked teeth but sometimes it is better to take a proactive approach, rather than waiting for the tooth to split before you do anything about it.

Removing the crack and placing a filling is a good option if the existing filling and crack is small. Removing the existing filling and crack and placing a crown over the tooth is the optimal long-term option, as this gives the tooth strength.

What our patients say

On my recent visit I took my little boy for his first dental experience. The staff were wonderful and hygienist Alex did an amazing job of making him feel comfortable and ensuring he had an enjoyable experience. He had no complaints and even talks about when we will go back to the dentist. As my dental experience as a child was terrible, I could not recommend Alex and the team highly enough for a visit for children to make them comfortable and a positive experience.

I went for a routine check up and clean as a new customer to the practice. From checking in (Abby) to the clean (Dr Chantal and Kian), everyone was very professional and thorough. A very comprehensive assessment was made and a meticulous clean was provided by Dr Chantal. Overall great dental experience and I will be back.

I am a white knuckle dental patient (a product of school mobile dental care back in the 1960’s) I had a crown installed all in one visit today (less than 3 hours). Totally painless. All staff were wonderful and highly empathetic to my issues. The practice is highly recommended, which is why I have been a patient at Kedron for the last 15 years.

I have been going to Kedron Family Dental for a while now and such positive experiences so far at the practice. Dr Chantal and the dental assistants that work there are fantastic - professional and takes good care of your oral health. I would keep going back despite having moved to the other side of the river :))

Elwynn has been my dentist for many years, and without a doubt is one of the best! Extremely professional and knowledgeable; but where he is really ahead of the rest, is the care and explanation he provides throughout any treatment or examination. Great to have him in the Brisbane area!
