How Fracture Depth Determines Treatment
A tooth has three layers: hard enamel outside, softer dentine containing nerve extensions, and the pulp with vessels and nerves. Which layer the fracture reaches determines both symptoms and treatment.
Enamel fracture — superficial
Small chips and cracks limited to the outer layer cause no pain. Treatment is simple: smoothing the edge and a small composite addition if needed.
Dentine fracture — sensitivity begins
Once the fracture reaches dentine, sensitivity to cold, heat, sweet and air begins, because microscopic tubules leading to the pulp are exposed. These should not wait, as bacteria contaminate them quickly.
Pulp exposure — an emergency
A pink or red point on the fracture surface means the pulp is exposed. This is an emergency: exposed pulp becomes infected within hours. Early treatment can sometimes keep the pulp vital, especially in young patients.
Root fracture — the most difficult group
If the fracture extends below the gum line, assessment is entirely different and needs radiographs. Fractures near the root tip may be splinted; those near the gum line often require extraction.
How to Store a Broken Tooth Fragment
This is the step patients most often neglect, yet it affects the outcome most.
The correct method
- Bring it in milk, saline or clean water in a closed container
- Do not scrub, brush or disinfect it
- Do not wrap it in a dry tissue — moisture loss ruins colour and fit
- Bring all pieces if there are several
- Come even if you cannot find it — it can be rebuilt with composite
Why bonding the original fragment is better
The original fragment has the tooth's own enamel structure, colour and translucency, which composite cannot fully imitate — a difference most visible on front teeth.
Repair Options for a Broken Tooth
The method depends on how much tissue was lost, where the fracture is, and how sound the remaining walls are.
Composite repair
The first choice for small and medium fractures: composite is layered, shaped and polished in a single session with minimal loss of sound tissue.
Veneers and crowns
With extensive loss, composite lacks durability and a porcelain veneer or crown is used. A veneer covers only the front surface; a crown encircles the whole tooth.
When root canal treatment is needed
If the pulp is exposed or has lost vitality, root canal treatment comes first. Pulp can die months after trauma, so follow-up matters; darkening of the tooth is a warning sign.
Temporary measures in the emergency session
At night the priority is smoothing sharp edges, covering exposed dentine and sealing any pulp exposure. Definitive aesthetic work is planned for a daytime appointment.
Broken Teeth in Children
In children, fractures most often affect the front teeth after falls. The approach differs from adults in several ways.
Milk tooth or permanent tooth?
In milk teeth the priority is protecting the developing permanent tooth beneath. In newly erupted permanent teeth the root may still be forming, so keeping the pulp vital is a priority.
Mouthguards in sport
Front tooth trauma is common in basketball, football, boxing and cycling. A custom-made mouthguard markedly reduces this risk.
