Crown lengthening a surgical procedure carried out by dentist to expose a greater amount of tooth structure for the purpose of restoring the tooth. This procedure involves excessing small amount of gingival tissue around the tooth. Furthermore, it is important to understand the excessive gums (gummy smile). The most common conditions requiring crown lengthening are: teeth that are too short, tooth decay that is severe below the gum line, or a broken or fractured tooth beneath the gum line. When a tooth experiences severe decay or breaks, the healthy area that remains is reduced.<\/p>\n\n\n\n

Who is this article for?<\/strong><\/h3>\n\n\n\n

This article is for patients who have been advised crown lengthening before a dental crown, bridge, veneer, or tooth restoration. It is also useful for patients with a broken tooth near the gumline, decay below the gum, short teeth, gummy smile, uneven gum levels, or difficulty getting a proper crown fit. Crown lengthening is not needed for every crown, but it becomes important when there is not enough visible tooth structure for a safe and stable restoration.<\/p>\n\n\n\n

What is crown lengthening?<\/strong><\/h3>\n\n\n\n

Crown lengthening is a dental procedure in which the gum tissue, and sometimes the supporting bone, is reshaped to expose more of the natural tooth. This gives the dentist better access to the tooth and creates enough space for a filling, crown, or other restoration. It may be done for functional reasons, aesthetic reasons, or both.<\/p>\n\n\n\n

Why is crown lengthening required?<\/strong><\/h3>\n\n\n\n

Crown lengthening may be required when a tooth is too short to hold a crown properly, when decay extends below the gumline, when a tooth is broken near the gum, or when an old crown margin is too deep. Without adequate tooth structure, a crown may not fit well, may come loose, may irritate the gums, or may fail early. The aim is to create a healthier foundation before placing the final crown.<\/p>\n\n\n

Crown lengthening before a dental crown<\/strong><\/h3>\n\n\n\n

A dental crown needs enough tooth height and clean margins to sit securely. If the tooth is broken or decayed below the gum, the dentist may not be able to prepare a proper crown margin. Crown lengthening helps expose sound tooth structure so the final crown can be shaped, fitted, and sealed more predictably.<\/p>\n\n\n\n

Crown lengthening for broken teeth<\/strong><\/h3>\n\n\n\n

When a tooth breaks close to the gumline, it may still be possible to save it if the root and remaining tooth structure are healthy. Crown lengthening can expose more tooth surface so that root canal treatment, post and core, and crown placement can be planned. However, if the fracture extends too deep into the root, extraction may still be required.<\/p>\n\n\n\n

Crown lengthening for decay below the gumline<\/strong><\/h3>\n\n\n\n

If tooth decay extends under the gum, it becomes difficult to clean, fill, and seal the tooth properly. Crown lengthening may help the dentist access the decayed area, remove infection, and restore the tooth with a filling or crown. This can improve the chances of saving the natural tooth.<\/p>\n\n\n\n

Crown lengthening for gummy smile<\/strong><\/h3>\n\n\n\n

In some patients, teeth look short because they are partly covered by excess gum tissue. Crown lengthening or gum reshaping may be used to expose more of the natural tooth and improve smile proportions. This is usually an aesthetic procedure and should be planned carefully according to tooth size, gum level, lip movement, and facial balance.<\/p>\n\n\n\n

Is crown lengthening always surgical?<\/strong><\/h3>\n\n\n\n

Crown lengthening may involve only gum reshaping in some cases, while other cases may require reshaping of both gum and bone. The decision depends on how much tooth structure needs to be exposed and how close the restoration margin is to the supporting bone. The dentist or periodontist decides this after clinical examination and X-rays.<\/p>\n\n\n\n

What happens during crown lengthening?<\/strong><\/h3>\n\n\n\n

The area is usually numbed with local anaesthesia. The dentist reshapes the gum tissue and, if required, adjusts a small amount of bone around the tooth. The gum is then positioned to expose the required amount of tooth structure. Healing time is needed before the final crown or restoration is placed.<\/p>\n\n\n\n

During the\u00a0dental crown<\/a>\u00a0lengthening\u00a0procedure,\u00a0excess gum and bone tissue is reshaped. Teeth and gums will be\u00a0a\u00a0little sensitive for some time following the procedure. So usually patients are advised to avoid very hot or cold drinks and food for a while. Furthermore, the patient may be advised not to brush or floss near the area of the procedure. There may be moderate, occasional bleeding of gums seen. An ice pack should reduce the swelling during the first hours of surgery. Patients told to avoid alcoholic beverages or smoking tobacco products for early recovery.\u00a0\u00a0<\/p>\n\n\n\n

Preparing for Treatment<\/strong><\/h3>\n\n\n\n

This procedure can often be completed in about an hour. Before your surgery, x-rays will be taken. Your medical history will also be reviewed with your dentist or surgeon to go over any current medications you are taking or any other health concerns that could potentially affect the surgery outcome. A thorough examination of your teeth, gums, and bone structure will be performed before your treatment. Additionally, to better help determine if crown lengthening surgery is right for you, your dentist will predetermine how much of the gums will need to be removed or contoured to achieve your desired results. <\/p>\n\n\n

How long does healing take after crown lengthening?<\/strong><\/h3>\n\n\n\n

Initial healing may take a few weeks, but final gum stability may take longer depending on the extent of the procedure, oral hygiene, gum thickness, bone reshaping, and the tooth being treated. The final crown is usually planned only after the gum has healed and the margin is stable.<\/p>\n\n\n\n

Risks and limitations of crown lengthening<\/strong><\/h3>\n\n\n\n

Like any dental procedure, crown lengthening has limitations. It may cause temporary sensitivity, gum tenderness, longer-looking teeth, food lodgement, or aesthetic changes. It may not be suitable if the tooth has poor root support, severe bone loss, deep fracture, or poor crown-to-root ratio. In such cases, extraction and replacement may be more predictable.<\/p>\n\n\n\n
