I Need Help With a Crack in Tooth
Understanding a Cracked Tooth
Noticing a crack in tooth enamel can feel worrying, especially if you’re unsure how serious it might be. Some cracks are small and cause no symptoms, while others can lead to pain, sensitivity, or infection if ignored. Sometimes cracks are obvious, other times there might be hairline crack in your tooth – having a dentist assess the situation is the best way to know what’s happening. At Gentle Dental Centre, you’ll always be met with care and no judgement — just clear advice and practical solutions.


Common Causes of a Tooth Crack
Cracks in teeth can develop for many reasons, including:
- Chewing hard foods such as nuts, ice, or hard lollies
- Accidental trauma from sports or falls
- Teeth grinding (bruxism), often during sleep
- Weakened teeth from large fillings or earlier dental work
Symptoms of a Cracked Tooth
Not every crack is painful, but you may notice:
- Sharp pain when biting or chewing
- Sensitivity to hot, cold, or sweet foods
- Pain that comes and goes
- Swelling near the gum around the cracked tooth
- A loose tooth
Even if symptoms fade, the crack may still worsen, so it’s important to have it checked early.


Why a Crack in Tooth Needs Attention
It can be tempting to wait and see if a cracked tooth settles down, but teeth cannot heal themselves. Leaving a crack untreated can allow bacteria to enter the inner layers of the tooth, leading to decay, infection, or even tooth loss. It can also lead to larger parts of the filling or tooth coming off or in uncommon situations, splitting the tooth in half or completely cracking off the tooth. Early treatment often means simpler, more affordable solutions — and less discomfort overall.
Treatment Options for a Cracked Tooth
- Dental bonding to seal minor cracks
- Fillings
- Crowns to strengthen and restore function
- Root canal treatment if the pulp has been affected
- Tooth extraction and replacement in severe cases where the tooth cannot be saved
Whenever possible, we focus on preserving your natural teeth and finding a treatment plan that suits you.

When to See a Dentist

FAQs About Cracked Tooth
Is a cracked tooth serious?
Yes, it can be. Even small cracks create an entry point for bacteria, which can lead to decay or infection. That’s why early assessment is important.
Will a crack in a tooth heal by itself?
No. Teeth cannot repair cracks naturally. Professional treatment is needed to stop the damage from getting worse.
Can cracked teeth be fixed?
Yes. In most cases, a cracked tooth can be repaired with treatments such as bonding, crowns, or root canal therapy. The best option depends on how deep the crack is.
Can a hairline crack in a tooth heal itself?
No. Teeth cannot regenerate or heal cracks on their own. A dentist can determine if the crack is only superficial or if it needs treatment to prevent further damage.
How long can a cracked tooth go untreated?
Leaving a cracked tooth untreated increases the risk of pain, infection, and even tooth loss. It’s best to see a dentist as soon as possible, even if the tooth isn’t hurting yet.
How do I know if my tooth crack is serious?
Some cracks are surface-level, while others extend deeper. A dental examination is the only way to know how serious it is.
Can I leave a cracked tooth if it doesn’t hurt?
Even without pain, bacteria can enter through the crack and cause problems later. Treatment is recommended to protect the tooth.
What should I do if my tooth cracks suddenly?
Rinse your mouth with warm water, avoid chewing on that tooth, and book an appointment at Gentle Dental Centre as soon as possible.
