Chipped front tooth: reattaching the piece, composite, veneer or crown?

Key points in brief

• A chipped front tooth is most often repaired with tooth-coloured composite or with your own reattached piece, usually in one visit. Larger losses may need a veneer or crown.
• The depth of the break decides whether the pulp, the nerves and blood vessels inside the tooth, needs protecting first. Reattachment depends on whether the broken piece is whole.
• After a blow, show the tooth to a dentist, ideally on the day of the injury, even if nothing hurts. Bring the broken piece in milk or saline.
• A red spot at the break, loose or shifted tooth: see a dentist that day. Loss of consciousness, vomiting or confusion after injury need a hospital emergency department or 112.
• Attend pulp check-ups, usually at 6–8 weeks and one year. After pulp exposure or if the tooth moved, they are more frequent and a veneer or crown usually waits.

How deep the break goes and why that decides the method

Chipped front teeth are repaired in different ways, depending on how deep the break goes. If it is shallow, smoothing or building up the edge of the tooth is usually enough, whereas a deep break needs the pulp protected first. A central incisor, one of the middle front teeth, has three layers. On the outside is the enamel, beneath it the dentine, and in the centre the pulp. The deeper the break, the closer bacteria from saliva can get to the pulp.

A chipped front tooth that has lost only enamel usually does not hurt and has a sharp, slightly translucent edge. When dentine is exposed, you can see a yellowish, matt surface, and the tooth often reacts to cold and air. If pink shows through where the tooth broke, the pulp lies just beneath the surface. A red or bleeding spot means that it is exposed.

What happened to the tooth as a whole matters too. A blow can loosen it or push it out of place, even when the chip itself looks harmless. The timing of the check-ups also depends on this.

In children and teenagers a broken front tooth is treated differently, because the gum and bone around the tooth are still changing.

How soon to show the tooth to a dentist

If your front tooth chipped from a blow, show it to a dentist as soon as possible, ideally on the day of the injury, even if nothing hurts. If you can see a red spot where it broke, or the tooth is loose or has changed position, show it the same day to the nearest available dentist or to an emergency dental service. You can plan a thorough examination and further treatment at Modern Dental & Orthodontics over the following days.

Sometimes the edge of the tooth, its biting edge, chips while you are eating, without any blow. If there is no red spot, no pain that comes on by itself and no swelling, the tooth can usually wait until the next working day. Until then, do not let the broken piece dry out, and read what to do until your appointment when a piece of tooth has broken off.

Loss of consciousness, vomiting, drowsiness or confusion after the injury require a hospital emergency department (SOR) or a call to 112. The same applies to shortness of breath, difficulty swallowing or breathing, swelling spreading down to the neck or up under the eye, and a high fever with feeling unwell.

What to find out from the dentist at the first visit after the injury

Bring the broken piece to your first visit with a chipped front tooth, in a small container of milk or saline solution - even if it looks useless. It is worth asking:

• How deep does the break go, and is the pulp exposed?
• Has this tooth, or have the teeth next to it, been loosened or moved?
• Is my broken piece suitable for reattaching?
• Is what you do today a permanent repair, or a stage before a veneer or crown?
• When should I come back for a check-up, and which symptoms are a reason to come sooner?

The dentist will usually also take an X-ray and check how the tooth responds to cold. Later on, they will compare what the check-ups show with these results. Write down the date of the injury and what you are told, especially if later visits will be at a different practice from the first one.

Enamel, dentine or pulp: what the dentist does with or without the broken piece

First, the dentist assesses how deep the break goes. Then they check whether there is a whole piece that has not dried out before the visit. Whatever the method, the dentist chooses the colour at the start of the visit, while the tooth is still moist. They also set a date for a pulp check-up. If the tooth was also loosened or moved, check-ups are more frequent and continue for longer than after a break alone.

A break in the enamel only

• The piece is whole: the dentist may reattach it.
• There is no piece, or it is tiny: smoothing the sharp edge or a small repair with composite applied in layers is enough.

A slightly chipped front tooth - with the loss limited to the enamel - usually does not need a big procedure. Smoothing takes a few minutes and in typical cases needs no anaesthetic. The pulp check-up usually falls at 6–8 weeks and at one year, especially after a blow.

A break through enamel and dentine, with the pulp covered

• The piece is whole and has not dried out: the dentist may reattach it.
• There is no piece, or it has crumbled: the dentist rebuilds the missing part with composite.

Exposed dentine has to be covered. The dentist may then suggest an anaesthetic, especially if the edge of the break needs smoothing. The check-ups are the same as for a break in the enamel.

A break close to the pulp or with the pulp exposed

When the pulp shows pink through a thin layer of dentine but is not exposed, the dentist first places a protective layer over the dentine and then rebuilds the tooth. An exposed pulp does not automatically mean root canal treatment. If the dentist judges that the pulp can be kept, they usually remove only its top layer and cover the wound with a medicated material. This procedure is called a partial pulpotomy. Only then does the dentist rebuild the tooth, at the same visit or within a few days.

• The piece is whole: it can be reattached once the pulp has been protected.
• There is no piece: the missing part is rebuilt with composite.

If the pulp was not exposed, the check-ups are the same as for a shallower break. After treatment of an exposed pulp they are more frequent: usually at 6–8 weeks, at 3 and 6 months, and at one year. When the pulp cannot be kept, the dentist usually opts for root canal treatment.

When a lot of the tooth is missing

When a large part of the edge is missing, or you also want to change the shape or colour of several teeth, the dentist may suggest a veneer, a thin shell over the front of the tooth. If the tooth has lost a large part of its walls, a crown can be safer. Pulp check-ups are the same as for a break of the same depth. Root canal treatment is sometimes also needed before a crown that has to rest on a post, a reinforcement fixed in the root canal.

When reattaching your own broken piece makes sense and how long it holds

A broken-off piece of a front tooth is suitable for reattaching when it is whole or almost whole and fits the tooth exactly. It also matters that it is kept in milk or saline solution until the visit. A piece that has dried out does not bond as well and may differ in colour. The dentist will judge whether it can still be used.

After reattachment the tooth keeps its own enamel, shape and colour, and the procedure itself is usually short. After 5 years, however, a reattached piece is still holding in roughly 3 teeth out of 4. It also needs another procedure more often than composite does. It comes off more often in older people and when the break exposed the pulp.

Even so, for a chipped front tooth with a whole piece, reattachment can be a good first choice. A reattached edge usually wears in a similar way to the neighbouring teeth, while composite may lose its shine and colour over time. If the piece comes off, the tooth can be built up with composite.

Composite, veneer or crown: how much tooth is missing and matching the colour

If there is no piece, or it is not suitable for reattaching, the dentist usually rebuilds the chipped front tooth with composite. Guidelines recommend this method for losses along the edge of the tooth, including after an injury.

In adults who do not clench or grind their teeth, composite on a broken upper front tooth was in good condition after 4 years in more than 9 cases out of 10. When a front tooth has chipped without a blow, the dentist also checks your bite and whether you clench or grind your teeth. Whether the new edge holds may depend on this.

A veneer is an option when a large part of the edge is missing and enough enamel remains around the gap for the veneer to be bonded to it. A composite veneer is made by the dentist in the practice, usually in a single visit. For a ceramic veneer the dentist grinds away a thin layer of enamel, and the veneer itself is made by a dental technician, so it usually takes 2–3 visits. If, after an injury, you would also like to improve the appearance of several teeth, veneers and composite bonding let you plan the shape and colour of all of them at once.

A crown covers the tooth on all sides, so the tooth has to be ground down all the way round. The dentist suggests one when the tooth has lost a large part of its walls and a veneer would have nothing to rest on. So whether a veneer or a crown is the better choice depends on how much of your own tooth remains around the gap.

The dentist chooses the colour in good light, while the tooth is still moist. A tooth that dries out while your mouth is open looks lighter after just a few minutes. That is why, for a day or two after the procedure, the repaired edge may differ slightly in colour from the neighbouring teeth, until the tooth is moist again.

Why a veneer or crown sometimes waits until the pulp check-ups

The dentist usually holds off on a veneer or crown when the pulp was exposed or the tooth was loosened or moved. A veneer or crown placed earlier would hide the colour of the tooth, which helps to judge whether the pulp is alive. Grinding the tooth down for a crown can also put extra strain on the pulp soon after an injury. If the pulp then died, root canal treatment would mean drilling through the new crown.

After an injury the pulp may heal or it may die. If it is dying, this usually shows within the first 2 years. The first repair - with composite or the reattached piece - is, however, usually done straight away, because it covers the dentine and protects the pulp from bacteria.

When the tooth was neither loosened nor moved and the pulp stayed covered, the pulp dies in roughly 1 tooth in 16. When the tooth was also loosened or moved, the pulp dies in 1 tooth in 4 or more often, especially if the tooth was pushed out of place.

With an exposed pulp, the dentist may perform a partial pulpotomy. When the tooth was not moved or badly loosened and the procedure was done within 24 hours of the injury, the pulp stays alive in roughly 9 teeth out of 10. If the procedure fails, the tooth often starts to hurt by itself within the first few weeks, without biting and without cold. However, the pulp can also die after a few months, and without pain.

At check-ups in the first weeks, or even months, after the injury, the tooth may not respond to cold. This lack of response can be temporary - on its own it is not a reason for root canal treatment. If the front tooth starts to darken, the dentist assesses whether a grey tooth after an injury still has a living pulp.

What happens after a chipped front tooth is repaired?

The colour and shape of the front tooth can be refined later. First it has to be confirmed that the pulp has survived the injury, so come to all the scheduled check-ups, even when the tooth does not hurt. Report pain that comes on by itself, swelling of the gum or darkening of the tooth straight away, without waiting for the check-up date.

Frequently asked questions

Will the reattached piece be the same colour as the rest of the tooth?

Usually yes, because it is the tooth's own enamel and dentine, so a reattached piece matches its colour most faithfully. Right after the procedure the tooth and the piece may look lighter, because they dry out during treatment. The colour usually returns to normal within a day or two. Close up, a thin line is sometimes visible where they join, which the dentist can mask with composite.

Does repairing a chipped front tooth affect speech or biting into food?

The repair does not usually change your speech permanently. For a few days your tongue will feel the new edge, and some sounds may come out slightly differently. You can bite into food, but more carefully, because composite and a reattached piece chip most easily at the edge of the tooth. Do not bite your nails, pens or thread. Cut an apple or a crusty roll into pieces and chew them with your back teeth.

Can an injury to a front tooth also damage neighbouring teeth that look intact?

Yes. A blow can loosen a neighbouring tooth or damage its pulp or root, even though from the outside the tooth looks untouched. That is why the dentist also examines the teeth next to it and the lower teeth, and checks their roots on the X-ray. Teeth that took the blow, even if they look intact, are also checked with a cold test at the follow-up visits.

Should someone who plays sport wear a mouthguard after a front tooth has been repaired?

Yes, if it is a sport in which blows to the face are common, such as football, basketball, hockey or martial arts. A mouthguard then protects the repaired front tooth and the other teeth. While the tooth is healing, it is better to give up contact sports altogether and to agree with the dentist at a check-up when you can return to training. A night guard worn for teeth grinding does not replace a sports mouthguard.

Can a repaired front tooth chip again in the same place?

Yes, because the edge of the tooth takes the greatest load when you bite into food. Composite can chip and a reattached piece can come off, most often in the first few years. The dentist can usually fix a small chip by adding composite, without replacing the whole repair. If the piece has come off whole, put it in milk or saline solution and bring it to your visit, because it can sometimes be reattached once more.

Can the front tooth be sensitive to cold and to biting in the first days after the injury and repair?

Yes, for a few days the tooth may be sensitive to cold and sore when you bite, especially if the break reached the dentine or the tooth was loosened by the blow. These symptoms usually ease day by day. Pain that comes on by itself, wakes you at night or gets worse instead of easing should be reported the same day.

What should you watch for in the first weeks after the repair, before the pulp check-up?

Come in straight away, without waiting for the check-up date, if the tooth starts to hurt by itself, darkens or becomes increasingly loose, and also if a swelling or a small pimple-like bump appears on the gum next to it. Such symptoms may mean that the pulp is dying or that an infection has developed. Until the check-up, brush your teeth thoroughly, including around this front tooth, and do not bite hard food with it.
