Crown lengthening surgery in Brookline MA exposing tooth structure at Smile Brookline Beacon Street

Surgical Preparation

Crown lengthening in Brookline, MA is a surgical procedure that removes a small amount of gum tissue and bone to expose more of the tooth, so a crown or filling has enough sound structure to grip. We treat patients from Coolidge Corner, Brookline Village, Chestnut Hill, Newton, Allston and Brighton before restorative work begins.

Dr. Yumi Ogata, a board-certified periodontist and associate professor of periodontology at Tufts, performs crown lengthening here, and Dr. Sara Stock, DDS plans the restoration that follows. The two are designed together, because the amount of tooth exposed has to match what the final restoration requires.

The Challenge

When a Tooth Needs Crown Lengthening to Be Restored

Understanding Biologic Width

A molar has fractured at the gumline, or decay has tracked below the margin where the drill cannot reach cleanly. Your dentist has explained that there is not enough tooth left above the gum to hold a crown, and that the alternative is extraction. It seems strange that a millimetre or two should decide the fate of a tooth, but it does, and the reason is biological rather than mechanical.
Every tooth has a zone of attachment between the bone and the base of the gum pocket, sometimes called the biologic width or the supracrestal tissue attachment. A restoration margin placed into that zone causes chronic inflammation, bone loss and eventual failure. Crown lengthening repositions the tissue and bone apically so the margin can sit above the attachment, giving the restoration a clean, sealable edge and the tooth a realistic prognosis.

Understanding Your Treatment

What Is Crown Lengthening?

The Science of Supracrestal Attachment

Crown lengthening is a periodontal surgical procedure that exposes additional tooth structure by repositioning gum tissue and removing a measured amount of bone around the tooth. It is performed when a fracture, decay or a previous restoration extends too close to the bone for a new crown or filling to be placed predictably.

The biological requirement is the attachment zone between the bone crest and the base of the gum sulcus, typically around two millimetres. A restoration margin encroaching on this zone provokes chronic inflammation and progressive bone loss. Surgery re-establishes the necessary clearance so the restorative margin can be sealed and maintained.

Benefits of Crown Lengthening

Saves teeth otherwise extracted

Saves the ToothMakes restoration possible where extraction was the alternativeSealable MarginAllows the crown edge to sit on sound, cleanable tooth structurePrevents InflammationRestores the attachment clearance that keeps tissue healthyBetter Crown RetentionProvides the height a crown needs to resist dislodging forcesDocumented StabilityOutcomes at six months and beyond are well described clinically

Crown Lengthening vs. Alternatives

When a margin sits too close to bone, the options are to move the tissue, move the tooth, or replace the tooth.

Is This Right for You

Who Is a Good Candidate for Crown Lengthening?

Deciding Whether a Tooth Is Restorable

Crown lengthening is indicated when a tooth is worth saving but cannot be restored without exposing more structure. The judgement is whether enough sound root will remain, supported by adequate bone, once the necessary height has been removed.

Ideal Candidates for Crown Lengthening

  • Patients with a tooth fractured at or just below the gum margin
  • Anyone with decay extending below the level of the existing gum tissue
  • Teeth with insufficient clinical height to retain a dental crown
  • Patients whose existing restoration margin is causing persistent local inflammation
  • People with healthy periodontal status on the neighbouring teeth

Who Should Consider Another Option

  • Teeth where removing the required bone would compromise the neighbouring teeth
  • Cases where the remaining root would be too short to support a restoration
  • Patients with a vertical root fracture, where tooth extraction is the realistic outcome
  • Anyone with untreated periodontal disease, which is stabilised before elective surgery
  • Patients on antiresorptive medication or with a history of jaw radiotherapy, who need medical review first

Bone removed at surgery does not return, so the amount is planned from the restorative requirement rather than estimated in the chair. General clinical guidance on periodontal surgery is available through the American Dental Association.

Your Experience

What Happens During Crown Lengthening Treatment

Step-by-Step Process

  1. Planning

    Dr. Ogata and Dr. Stock agree how much structure the planned restoration requires.

  2. Anaesthetic

    Local anaesthetic numbs the tooth and surrounding tissue completely.

  3. Access

    A small flap is raised to expose the bone crest around the tooth.

  4. Recontouring

    A measured amount of bone is removed to re-establish attachment clearance.

  5. Closure and Healing

    The flap is sutured at the new level and the site heals for six to twelve weeks.

Risks and Side Effects

What to Know

Common Crown Lengthening Side Effects

Soreness, swelling and minor bleeding for five to ten days is normal. The treated tooth is often sensitive to cold once additional root surface is exposed, and that usually improves over several weeks. Sutures can feel irritating until removed at one to two weeks.

Expected Changes and Less Common Complications

The tooth will look longer afterwards, and a small dark triangle can appear between it and its neighbour where tissue has been repositioned. Root sensitivity may persist in some patients. Because bone support is reduced by design, mobility can increase slightly, and in rare cases the tooth loosens more than anticipated. Infection and delayed healing are uncommon but possible.

Safety and Case Selection

Bone removal is permanent, and taking too much compromises the tooth or its neighbours. That is why the surgical plan is dictated by the restorative requirement and agreed between Dr. Ogata and Dr. Stock before surgery. Tell us about anticoagulants, antiresorptive medication, diabetes and smoking. Clinical background is available via the American Dental Association.

Investment

Crown Lengthening Cost in Brookline

Pricing and Payment Options

How Much Does Crown Lengthening Cost in Brookline?

Fees depend on how many teeth are involved and whether bone recontouring extends to adjacent teeth. Surgery on a single posterior tooth is straightforward, while a multi-tooth segment takes longer. Nationally, crown lengthening commonly ranges from about $1,000 to $3,000 per tooth or site. The restoration that follows is quoted separately, and both figures are given before surgery so the total is clear.

Insurance and Flexible Payment Options

Crown lengthening performed to make a tooth restorable is a functional procedure, and most dental plans contribute where documentation supports the need. Smile Brookline is fee-for-service and submits claims to all major commercial carriers on your behalf.

The Smile Brookline Difference

Why Choose Smile Brookline for Crown Lengthening in Brookline

Beacon Street Since 1992

Dr. Yumi Ogata performs the surgery and Dr. Sara Stock, DDS plans the restoration, in the same practice and from the same records. Crown lengthening removes bone permanently, so the amount taken must be dictated by what the final restoration needs, which is difficult to coordinate across two separate offices.

Common Questions

Frequently Asked Questions About Crown Lengthening

How much does crown lengthening cost in Brookline, MA?
Cost depends on how many teeth are involved and the extent of bone recontouring, commonly $1,000 to $3,000 per site nationally. The crown or filling that follows is quoted separately, and we give both figures before surgery. Because the procedure is functional, most plans contribute where documentation supports it.
How long does crown lengthening take?
The surgery itself takes 60 to 90 minutes. The important number is the healing interval: six to twelve weeks before final impressions, because tissue position must stabilise first. Taking impressions early risks a crown margin that ends up submerged once tissue rebounds.
Does crown lengthening hurt?
The procedure is performed under local anaesthetic and should be comfortable. Afterwards, expect soreness and swelling for five to ten days, managed with prescribed pain relief. The tooth is often sensitive to cold for several weeks once additional root surface is exposed.
When can I have my crown fitted?
Usually six to twelve weeks after surgery. Posterior teeth can often proceed at the shorter end, while teeth visible in the smile are given longer so the tissue level is definitely stable. Dr. Stock takes final impressions only once the margin position will not change.
How long do the results last?
The change is permanent, since bone and tissue have been repositioned rather than temporarily moved. Clinical follow-up shows stable outcomes when the correct clearance was established at surgery. Maintaining the result depends on daily cleaning around the new margin and regular periodontal review.
What is the difference between crown lengthening and gum contouring?
Crown lengthening is a functional surgical procedure that removes bone as well as tissue so a restoration can be placed on sound structure. Gum contouring reshapes soft tissue only, for appearance. They involve different depths, different healing and different purposes.
Can men and women of any age have crown lengthening?
Yes, provided periodontal health and bone support are adequate. Age is not the limiting factor. What matters is whether enough sound root remains after the required height is removed, and whether the neighbouring teeth can tolerate the bone recontouring involved.
Will the tooth look longer afterwards?
Yes, and that is the intended outcome. Additional tooth structure has been exposed so the restoration can grip it. On back teeth this is rarely noticeable. On teeth visible when you smile, we plan the design carefully with Dr. Stock and discuss the appearance with you beforehand.
Is extraction a better option?
Sometimes, and we will say so. If the remaining root would be too short, if a vertical root fracture is present, or if the bone removal would damage the neighbouring teeth, then extraction followed by an implant is the more honest recommendation. Saving a tooth that will fail in two years serves nobody.
Will my tooth feel loose after surgery?
Slight increased mobility is common in the early weeks, because bone support has been deliberately reduced and the tissue is healing. It generally settles as healing completes. Mobility that increases rather than improves should be reviewed, and we check the tooth at suture removal and again before restoration.
