Sometimes a tooth that needs a crown does not have enough visible structure above the gum to hold it securely. In other cases, teeth look short because gum covers too much of them. Crown lengthening is a minor procedure that reshapes the gum, and sometimes a small amount of bone, to expose more of the tooth. It is a common step that can make the difference between a crown that lasts and one that fails.
A crown is held in place by the tooth structure it surrounds, much like a cap on a bottle. If a tooth has broken off near the gumline, or decay extends below the gum, there may not be enough tooth above the gum for the crown to grip. The edge of the crown would also sit too deep, where it is difficult to clean and can irritate the gum. Crown lengthening creates a healthy margin of exposed tooth so the crown can be fitted securely and the gum can stay healthy around it.
Crown lengthening is also used for cosmetic reasons. Some people have a gummy smile where the teeth look short because excess gum tissue covers them. Reshaping the gumline can reveal more of the natural tooth, making teeth look longer and more proportionate. It is often combined with veneers or crowns as part of a smile makeover, and it can be done on a single tooth to even out an uneven gumline.
The procedure is carried out under local anaesthetic. Depending on the case, the dentist may remove a small amount of gum tissue, or gently lift the gum to reshape a small amount of the underlying bone, then reposition and stitch the gum. The aim is to create the right amount of space between the bone and the edge of the future crown, which is essential for long-term gum health. Most procedures take around an hour, depending on how many teeth are treated.
Mild swelling and tenderness are common for a few days. Pain relief, cold compresses on the first day and soft foods help. You will be asked to avoid brushing directly on the treated area for a short time and to use a prescribed mouthwash or salt water rinses. Stitches are usually removed after about a week. Avoid smoking, which slows healing. Most people return to work the next day, though they may prefer to rest if several teeth were treated.
After crown lengthening, the gum needs time to heal and settle into its new position before the final crown is made. For back teeth this may be a few weeks; for front teeth, where appearance is critical, your dentist may wait longer so the gum level is completely stable. A temporary crown protects the tooth in the meantime. Rushing this stage can lead to the gum shifting after the final crown is fitted, leaving an uneven or visible edge.
In some cases, orthodontic extrusion, gently pulling the tooth up with braces, can achieve a similar result. If the tooth is severely damaged below the gum, extraction and replacement with an implant may be a more predictable option. Your dentist will explain the pros and cons of each option so you can make an informed choice.
It is done under local anaesthetic, so you should not feel pain during the procedure. Mild soreness afterwards is usually well controlled with standard pain relief.
Initial healing takes one to two weeks, but the gum may need several weeks to a few months to fully stabilise before the final crown.
Some sensitivity can occur as more tooth is exposed, but it usually settles. A sensitivity toothpaste can help.
