Dr. Li Attends Course on Gum Grafting and Crown Lengthening

By Pamela Li, in Articles, on January 20, 2014 | Comments (0)

visit to the dentistOTTAWA, Ontario – Dr. Pamela Li recently attended a continuing education course from the Perio Institute in Toronto in an effort to sharpen her skills and knowledge to better serve her patients. One of the topics covered was crown lengthening.

“Crown lengthening is a great option for patients with overly gummy smiles,” says Dr. Li. “Gummy smiles can be the result of too much gum tissue covering the tooth. Crown lengthening can also be performed to make a restorative or cosmetic dental procedure possible. If a tooth is decayed, broken below the gum line or doesn’t have enough visible structure to attach the restoration, crown lengthening can correct it.”

During the procedure, excess bone and gum tissue are reshaped to expose more of the tooth. A cosmetic dentist like Dr. Li, who serves patients in Ottawa, can do this to one tooth, then entire gum line, or several teeth to expose a broader and toothier smile. In the event that the patient needs a crown or bridge, but doesn’t have enough visible tooth to attach it, crown lengthening will adjust the gum and bone level so the tooth will be able to be restored properly.

“The course I attended was incredibly valuable,” says Dr. Li. “It covered both anterior, or front teeth and posterior or back teeth, lengthening. In anterior crown lengthening, we often are simply correcting gummy smiles by making teeth look longer. Posterior crown lengthening is used for short teeth, root decay and broken teeth.”

Crown lengthening is a surgical procedure during which the gingival tissue around the tooth is incised. The dentist or periodontist will make cuts in the tissue to pull the gum away from the bone, providing access to the tooth root and bone. The amount of gum tissue that will need to be removed will depend on the needs of the individual patient. Once enough of the tooth is exposed, the area will be cleaned and the gums will be stitched back together.

It is a minor surgery with a quick recover time, and stitches will typically resorb on their own within a week. Patients will receive a special oral rinse and care instructions to properly care for their mouth during recovery.

The other procedure covered during the course Dr. Li attended was gum grafting. In some patients, gum grafting is a necessary procedure to protect against the effects of gum recession, which can be damaging. Gum grafts can also be performed to improve the look of a patient’s smile.

“If a patient is experiencing gum recession that means the patient is losing gum and bone around their teeth,” says Dr. Li. “More of the root of the tooth will be exposed, and there is an increased risk of root decay. While it can be a common occurrence, it can lead to unattractive smiles and tooth sensitivity. Eventually, if not treated, it can even lead to tooth loss.”

To repair the damage, a gum graft may be needed. At the course Dr. Li attended, two types of grafts were discussed – connective tissue grafts and free gingival grafts.

Free gingival grafts are usually performed on the back teeth, or areas not typically seen. Using tissue from the roof of the mouth, a small amount will be removed and then attached to the gum area in need. This type of graft works well in patients who have thin gums and require additional tissue to reinforce their gums.

Connective tissue grafts are used in esthetic areas. A flap of skin will be removed from the roof of the mouth. Under the flap lies a tissue called the subepithelial connective tissue. This will also be removed and stitched to the gum tissue that surrounds the exposed root. Once the connective tissue has been removed, the flap will be stitched back down. Connective tissue grafts are typically performed in the front or more esthetic areas of a patient’s mouth. The tissue can reattached to the exposed root area, and will decrease sensitivity on the roots.

Just as with a crown lengthening procedure, recovery from a gum graft will take about a week to two weeks. Patients will be given a special rinse to help control plaque during the healing process, and in some cases, patients will be put on an antibiotic to reduce the possible infection risk. Patients should refrain from flossing and brushing the gum line that was repaired until it has fully healed.

If you think you may be a candidate for either procedure, contact Dr. Li’s office today. She is committed to helping her patients achieve their best smiles and maintain their best oral health, and her commitment to quality care is evidenced by her desire to continue her education and advance her skill set.

Problems Associated with Protruding Teeth and How to Correct Them

By Pamela Li, in Articles, on May 8, 2012 | Comments (0)

OTTAWA, ONTARIO – Protruding teeth can create a number of issues for your child. Eliminating the habits that cause teeth to protrude and correcting their teeth as early as possible can alleviate problems later in life.

“Many children have orthodontic problems that develop at an early age,” said Ottawa cosmetic dentistry professional Dr. Pamela Li. “Although orthodontic problems can be treated later with traditional braces, there are some issues that should be treated as soon as they develop. That’s the case with protruding teeth.”

Children with protruding teeth are at a greater risk of suffering from injury and trauma, especially during sports, as their teeth stick out past the lips. This makes it difficult for them to close their mouth completely. This can create a mouth breathing habit and it is also more difficult to make a comfortable sports guard. (more…)

World No Tobacco Day Takes Place May 31

By Pamela Li, in News, on April 3, 2012 | Comments (0)

OTTAWA, ONTARIO – May 31 is World No Tobacco Day, sponsored by the World Health Organization, which is the perfect time for dental professionals to highlight the effects of smoking on dental health.

The theme for 2012 is tobacco industry interference, and the day will focus on the need to expose and counter the tobacco industry’s brazen and increasingly aggressive attempts to undermine the WHO Framework Convention on Tobacco Control because of the serious danger to public health.

Smoking tobacco is an addiction, which can result in physical and psychological dependency. While smoking affects every part of the body, it is particularly harmful to the mouth.

“Despite the health threat and the likelihood of developing cancer, people are just not motivated to quit anymore,” said Dr. Pamela Li, an Ottawa cosmetic dentistry specialist. “The main effects of smoking on the mouth are gum disease, oral cancer, tooth and denture stains, bad breath and tooth loss.”


Dr. Pamela Li is Offering Free Cosmetic Consultations Through Dec. 21

By pamelali, in News, on October 22, 2011 | Comments (0)

OTTAWA, ONTARIO – Ottawa cosmetic dentistry professional Dr. Pamela Li recently announced a great holiday gift idea for people who seem to have everything except the perfect smile.  Through Dec. 21, Dr. Li will offer free cosmetic consultations for current and new patients.

The holidays are just around the corner, which means family photos, work parties and social gatherings are soon to follow. Instead of looking for the perfect outfit to wear or the most thoughtful gift to give, consider investing in your smile instead.

“During the holidays, people are reluctant to spend money on themselves,” said Ottawa implants dentist Dr. Li. “But the first thing people notice about you is your smile. If you are ashamed to smile during the most joyful time of the year, a cosmetic procedure is a gift you will never regret giving yourself.”


Using Laser Dentistry for Common Oral Ailments

By pamelali, in Articles, on September 21, 2011 | Comments (0)

OTTAWA, ONTARIO – Using lasers for various types of surgical procedures has not only made them safer, but has also greatly reduced recovery time.
Dental professionals can improve the look of your smile or treat gum disease using a laser, which is much less invasive than traditional periodontal surgery.

Cosmetic Gum Surgery
Some people have too much gum tissue or their gums may be uneven. Either way, Ottawa cosmetic dentistry provider Dr. Pamela Li says a laser gum re-contouring procedure can make a world of difference.

“Gummy” smiles are caused by an overgrowth of gum tissue or bone tissue, which dominates the mouth, making the teeth appear almost secondary in appearance. This can be due to heredity, improper development or caused by certain health problems or medications.


Offering Sleep Apnea Device

Ottawa, ON – Ottawa cosmetic dentistry expert Dr. Pamela Li now offers the Moses, an oral airway dilator which helps to treat sleep apnea and snoring. The two-part design of the appliance makes it comfortable for patients and allows them to talk, drink, open wide and close their lips.

“There are other products that are designed to prevent sleep apnea,” notes Li, an Ottawa teeth bleaching provider. “However, many of them are uncomfortable and hold the tongue in an awkward position.  They do not encourage forward positioning of the tongue.” (more…)

Offering a New Implant Denture System

By pamelali, in News, on April 17, 2011 | Comments (0)

Ottawa, ON – Dr. Pamela Li’s Ottawa dental clinic has been using a new system to provide dentures for their patients. The implant supported dentures have revolutionized how dentists think of and provide dentures.

The locator system by Nobel Biocare allows dentures to be anchored right in the mouth with dental implants embedded right into the jaw. Patients don’t need to fuss with denture adhesives or dentures that feel loose. The implant system allows for more natural feeling teeth, especially in the lower jaw. Many patients have trouble getting used to complete dentures in the lower jaw. However, the new system places two or four implants in the jaw – where they act like tooth roots, making a patient’s denture feel more comfortable. “My patients are happiest with four – rather than two – implants,” explains Li, an Ottawa cosmetic dentistry provider. “But that is a more expensive proposition.” (more…)

Treating Gum Disease

By Pamela Li, in Articles, on March 30, 2011 | Comments (0)

Ottawa , ON- Ottawa cosmetic dentistry provider Dr. Pamela Li has extensive experience treating periodontal – or gum – disease.  However, she notes that the causes, diagnosis, and treatment of gum disease are not well understood by many dental patients. Periodontal disease can be serious, and is the leading reason for tooth loss in Canadian adults.

The early stage of periodontal disease is gingivitis, in which plaque builds up, allows the accumulation of bacteria and causes the gums to be red and inflamed - and sometimes bleed during brushing and flossing. (more…)

How Veneers Work

By pamelali, in Articles, on February 10, 2011 | Comments (0)

Ottawa, ON – Veneers can entirely reshape a patient’s smile, as they are the perfect solution for treating many dental conditions.

They are more conservative than crowns, but are still very strong. Bonding with white filling material is another option to reshape a smile, but they need more maintenance and do not have the natural translucency and shine of porcelain, notes Dr. Pamela Li an Ottawa dental implants provider.

Porcelain veneers are fine ceramic shells that are bonded directly to the front and top of the teeth. They are growing increasingly popular because of their simplicity and versatility. With veneers as a choice, patients don’t need to suffer with gaps between their teeth – or teeth that are stained, misshapen or crooked. (more…)

Tooth Whitening Options

By pamelali, in Articles, on January 23, 2011 | Comments (0)

Ottawa, ON – Having whiter teeth is most patients’ number one concern about the way they look. In fact, the number of Americans who whiten their teeth has grown more than 300 percent since 1997. But, the Ottawa dental practice of Dr. Pamela Li offers a simple tooth whitening (sometimes called bleaching) process to brighten the color of your natural tooth enamel and enhance your smile.

A number of factors can cause staining or yellowing of the teeth, including: excessive fluoride, use of certain medicines during childhood, age, and consuming a lot of coffee, tea, or wine. “Many people find their teeth yellow as they get older,” explains Dr. Li  Ottawa tooth whitening specialist. “The enamel on your teeth thins out and just doesn’t give you that bright white look anymore. These patients are simply looking for a way to restore their teeth to their previous color.” (more…)
