A crown — a life-like “cap” made of dental porcelain that permanently covers an existing tooth — is an effective way to restore a still-viable decayed or broken tooth’s appearance. Properly fitting the crown over the tooth requires some healthy tooth structure above the gum line.
But what if the tooth has broken down to the gum line? In this case, we would need to perform a common procedure known as crown lengthening to expose more of the tooth.
Crown lengthening is a minor surgical procedure performed with local anesthesia to numb the tooth, surrounding gum tissues and supporting bone. We first make tiny incisions inside the gum-line on both the cheek and tongue side of the tooth to expose the bone, and then carefully remove a small amount of bone from either side of the tooth; this will expose or “lengthen” the tooth. Once finished, we suture the gum tissue back into place with self-dissolving sutures against the bone and tooth.
Most procedures take only sixty to ninety minutes, and the mild discomfort afterward is usually managed with pain relievers like ibuprofen. While the gum tissues may appear to be healed after a week, we typically wait six to eight weeks to perform the final crown restoration to give the tissues time to fully mature.
Crown lengthening may not work in all situations, especially with a severely fractured tooth. In these cases, we may need to evaluate the long-term viability of the tooth and consider other restorative options. Depending on your bite, it may also be necessary to treat with orthodontics first: not only will the tooth move into a better position, but the treatment may move both the gum and bone down with the tooth. Subsequent crown lengthening will then only affect the intended tooth and not adjacent ones, resulting in a more even smile.
The first step is for us to decide after a thorough examination if you would benefit from crown lengthening. If so, this minor surgical procedure could pave the way for better mouth function and a more attractive smile.
While tooth decay is a potential problem at any age, the risk increases as you grow older. Not only are senior adults more susceptible, decay is often more difficult to treat. That’s because cavities can occur at or below the gum line, often due to gum recession.
If that’s the case, we won’t be able to fill the cavity in the usual way because the gum tissue is in the way. To make it possible to treat, we may need to perform a minor surgical procedure known as crown lengthening.
As the name implies, the procedure helps expose more of the crown, the tooth’s visible part, from the surrounding gum tissue. In basic terms, we’re repositioning the gum tissue away from the biting surface of a tooth to make room for a filling. It’s also useful for improving a tooth’s appearance by making it look longer, or creating room for a crown or other dental restoration.
After applying a local anesthesia, the dentist (or periodontist, a specialist in the gums) creates a tiny flap of gum tissue with a series of incisions. This allows the dentist to move the affected gums out of the way to access the underlying bone. The dentist then reshapes the bone to adequately support the gum tissue when it’s finally repositioned to expose the crown. In its new and improved position, the dentist sutures the gum tissue in place.
For a few days afterward, the patient will need to restrict their diet to soft foods, avoid strenuous activities and apply an ice pack to help reduce swelling the day of surgery. They will also prescribe a pain reliever and possibly an antibiotic to reduce the chances of infection.
While most people return to normal activities a few days later, you’ll usually have to wait a few weeks for the gums to heal before undergoing any further treatments for the affected teeth. But even with the wait, crown lengthening could make it possible to not only save your tooth but improve your smile as well.

You have a lot of options for replacing missing teeth, from state-of-the-art dental implants to affordable, but effective partial dentures. But if the teeth in question have been missing for a while, you may first have to undergo orthodontic treatment. Here's why.
While they may feel rigid and firm in the jawbone, teeth are actually held in place by periodontal (gum) ligaments. These elastic tissues lie between the teeth and the bone and attach to both with tiny filaments. This mechanism allows the teeth to incrementally move over time in response to biting pressures or other environmental factors.
When a tooth goes missing the teeth on either side of the space naturally move or "drift" into it to help close the gap. This natural occurrence can reduce the space for a restoration if it has gone on for some time. To make room for a new prosthetic (false) tooth, we may have to move the drifted teeth back to where they belong.
If you're thinking metal braces, that is an option—but not the only one. Clear aligners are another way to move teeth if the bite problem (malocclusion) isn't too severe. Aligners are a series of custom-made, clear, plastic trays worn over the teeth. The patient wears each tray, slightly smaller than the previous one in the series, for about two weeks before changing to the next one. The reduction in size gradually moves teeth to their intended target position.
Many adults prefer clear aligners because they're nearly invisible and don't stand out like metal braces. They're removable, so you can take them out for cleaning or for special occasions. And, we can also attach a prosthetic tooth to the tray that temporarily covers the missing tooth space.
Whichever orthodontic treatment you choose, once completed we can then proceed with restoration to permanently replace your missing teeth. While it can be a long process, the end result is a beautiful smile that could last for years to come.

While the term “plastic surgery” might bring to mind face lifts or tummy tucks, not all procedures in this particular surgical field are strictly cosmetic. Some can make a big difference in a person’s health.
One example is periodontal plastic surgery, which corrects gum tissue loss around the teeth. Although these procedures can indeed improve appearance, they more importantly help save teeth.
Gum loss is most often a consequence of periodontal (gum) disease, a bacterial infection arising from a thin film of food particles on the teeth called dental plaque. As the disease weakens the gums’ attachment to teeth, they shrink back or recede, exposing the area around the roots. Without the protective cover the gums provide the roots, they become more susceptible to decay.
In milder cases of gum recession, treating the infection often results in the gums regaining their normal attachment to teeth. But with more advanced recession, natural gum healing may not be enough to reverse it. For such situations grafting donor tissue to the recessed area can help stimulate new tissue growth.
While gum tissue grafts can come from an animal or other human, the most likely source is from the person themselves. In one type of procedure, free gingival grafting, the surgeon locates and completely removes (or “frees”) a thin layer of skin resembling gum tissue, typically from the roof of the mouth, shapes it and then transplants it by suturing it to the recession site. Both donor and recipient sites heal at about the same rate in two to three weeks.
Another technique is known as connective tissue grafting. In this procedure the surgeon partially removes the donor tissue from its site while leaving a portion containing blood vessels intact. The palatal tissue is still used and transported to fit beneath the tissue that’s still attached to the blood supply. This connective tissue graft is then positioned and sutured to the recipient site while still maintaining its blood supply connection at the donor site. Maintaining this connection facilitates healing and increases the chances the graft will “take” and become firmly attached to the new site.
Grafting procedures require advanced techniques and skills. But with them we may be able to restore gum attachment to teeth with an impact on appearance and dental health that’s well worth the effort.

You may not always be able to tell if your child's bite isn't developing properly. Â That's why you should have them undergo an orthodontic evaluation around age 6 to uncover any emerging problems with tooth misalignment.
Still, there are some visible signs all's not well with their bite. As the primary (baby) teeth give way, the permanent teeth erupt sequentially around ages 6 to 8. As they come in, you should notice that each tooth fits uniformly next to each other without excessive gaps or, on the other end of the spectrum, not crowded together in crooked fashion. Upper teeth should also fit slightly over the lower teeth when the jaws are shut.
If their teeth appearance deviates from these norms, they may have a bite problem. Here are 4 abnormalities you should watch for.
Underbite or deep bite. As we mentioned, the front teeth should cover the lower teeth with the jaws shut. In an underbite, the reverse happens — the lower teeth are in front of the upper teeth. It's also a problem if the upper teeth cover the lower teeth too much (often referred to as “deeply”).
Open bite. This occurs when there's a gap between the upper and lower front teeth while the jaws are shut together. One possible cause is late thumb sucking, which can put undue pressure on the front teeth and cause them to develop too far forward while forcing the bottom front teeth further backwards.
Crossbites. This kind of bite occurs when some of the teeth don't fit properly over their counterparts, while others do. Crossbites can occur anywhere in the mouth, for example the upper front teeth fitting behind the lower front teeth while the back teeth overlap normally, or the reverse (front normal, back abnormal).
Misalignments and Abnormal Eruptions. Sometimes upper teeth may align too far forward, a situation known as protrusion. Conversely, lower teeth (or the jaw itself) may come in too far back (retrusion). Because a primary tooth might be out of position or not lost in the proper sequence, a permanent tooth might noticeably erupt out of its proper position.
If you notice any of these situations with your child's teeth see your dentist or orthodontist soon for a full examination. If caught early, we may be able to take action that will lessen or even eliminate the problem.
