Restoring chipped, stained or decayed teeth with dental porcelain is a tried and true method that’s been used for decades. In recent years, though, restorations made with composite resin have become a popular alternative.
Made of a plastic-based matrix with added glass filler, composite resin can be molded and bonded to teeth to replace missing structure with color to match. While they can’t be used for every problem situation, they’re an efficient and economical way to transform your smile.
Here are 4 advantages for using composite resin to restore moderately defective teeth.
They require very little tooth preparation. Crowns, veneers and other porcelain restorations require removing some healthy tooth structure to accommodate them. With the development of stronger bonding materials, composite resins can restore even many large defects in teeth caused by decay or trauma with little structural removal and still remain durable.
Most composite resin restorations are “single-visit” procedures. Unlike porcelain restorations, applying composite resin doesn’t require a dental lab, a process that can take multiple visits. In most cases, a skilled dentist can apply them during a single visit.
They have excellent color matching capabilities. We usually think of teeth as one single shade of white — actually, a single tooth can have varying gradations of color from the root to the tip. As mentioned before, composite resins can be prepared to match those color shades precisely, so your restored teeth look natural and blend well with your other teeth.
Composite resins can be an effective temporary fix for young injured teeth. Because children’s teeth are still developing, permanent restorations for traumatized teeth aren’t usually advisable until they’ve fully matured. Composite resin can be used to restore a young tooth’s form and function until it’s ready for a permanent solution.

A “gummy” smile, in which the upper gums are too prominent, is a common condition. There are several causes for gummy smiles — determining which one is the first step to having your appearance changed.
Although perceptions vary from person to person, most dentists agree a gummy smile shows 4 mm or more of gum tissue, and the amount is out of proportion with the length of the crown (the visible tooth). Teeth normally erupt through the gums during childhood and continue development until early adulthood, shrinking back from the tooth until stabilizing in place.
This typically produces a crown length of about 10 mm, with a “width to length” ratio of about 75-85%. But variations can produce differences in the relationship between teeth and gums and the width to length ratio of the teeth. The teeth may appear shorter and the gums more prominent. Worn teeth, caused by aging or grinding habits, may also appear shorter.
If tooth to gum proportionality is normal, then the cause may be upper lip movement. When we smile, muscles cause our lips to retract 6-8 mm from the lip’s resting position. If the amount of movement is greater (meaning the lip is hypermobile), it may show too much of the gums. The upper jaw can also extend too far forward and cause the gums to appear too prominent.
There are a number of ways to improve gummy smiles, depending on the cause. Periodontal plastic surgery known as crown lengthening removes and reshapes excess gum tissue to reveal more of the tooth. Lip hypermobility can be reduced with Botox injections (to paralyze the muscles) or in some cases with surgery to reposition the muscle attachments. Orthognathic surgery can be used to surgically reposition an overextended upper jaw. Other cosmetic enhancements such as orthodontics, bonding or porcelain restorations can also prove effective.
The first step is to obtain an accurate diagnosis for your gummy smile. From there, we can devise the best treatment approach to bring your smile back into a more attractive proportion.

Other than the common cold, tooth decay is the most prevalent disease in the world. And while a cavity or two may seem like a minor matter, tooth decay’s full destructive potential is anything but trivial. Without proper prevention and treatment, tooth decay can cause pain, tooth loss and, in rare cases, even death.
This common disease begins with bacteria in the mouth. Though these microscopic organisms’ presence is completely normal and at times beneficial, certain strains cause problems: they consume left over carbohydrates in the mouth like sugar and produce acid as a byproduct. The higher the levels of bacteria the higher the amount of acid, which disrupts the mouth’s normal neutral pH.
This is a problem because acid is the primary enemy of enamel, the teeth’s hard protective outer shell. Acid causes enamel to lose its mineral content (de-mineralization), eventually producing cavities. Saliva neutralizes acid that arises normally after we eat, but if the levels are too high for too long this process can be overwhelmed. The longer the enamel is exposed to acid, the more it softens and dissolves.
While tooth decay is a global epidemic, dental advances of the last century have made it highly preventable. The foundation for prevention is fluoride in toothpaste and effective oral hygiene — daily brushing and flossing to removing plaque, a thin film of food remnant on teeth that’s a feeding ground for bacteria, along with regular dental visits for more thorough cleaning and examination. This regular regimen should begin in infancy when teeth first appear in the mouth. For children especially, further prevention measures in the form of sealants or topical fluoride applications performed in the dentist office can provide added protection for those at higher risk.
You can also help your preventive measures by limiting sugar or other carbohydrates in your family’s diet, and eating more fresh vegetables, fruit and dairy products, especially as snacks. Doing so reduces food sources for bacteria, which will lower their multiplication and subsequently the amount of acid produced.
In this day and age, tooth decay isn’t a given. Keeping it at bay, though, requires a personal commitment to effective hygiene, lifestyle choices and regular dental care. Doing these things will help ensure you and your family’s teeth remain free from this all too common disease.

Your smile may look healthy, but something quite unhealthy may be going on behind it. Unbeknownst to you, periodontal (gum) disease could even now be damaging tissues and bone that could lead to tooth loss. Caused by plaque, a thin film of food remnant and bacteria built up on the teeth due to poor oral hygiene, gum disease can aggressively spread deep into gum tissues without you even realizing it.
If you pay close attention to your gums, however, it’s still possible to pick up signs of the disease, even during its early “silent” stage. As the infection progresses, the signs will become more frequent — and consequential.
Here are 4 signs of gum disease you should definitely keep on your radar.
Bleeding. Unless you’re doing it too hard, healthy gums won’t normally bleed when you’re brushing or flossing. If they do bleed with just light to moderate pressure, it’s a sign the tissues have been inflamed and weakened by the infection.
Inflammation and redness. If you notice your gums seem swollen or reddened, it could mean they’re inflamed. Inflammation is the body’s response for fighting infection — however, if the inflammation becomes chronic it can actually damage the tissue it’s trying to protect.
Abscesses. These are localized areas in the gums where the infection has become isolated. They’ll typically be more swollen than surrounding gum tissues and are often filled with pus. They can also be sensitive to the touch and painful. Any sore spot like this that lasts for more than a few days should be examined.
Loose or moving teeth. Teeth that can move in the socket or appear to have shifted their position are signs of an advanced stage of gum disease. It’s an indication the gum and bone tissue that hold teeth in place have been weakened and are losing their attachment. Without immediate treatment, it’s just a matter of time before the teeth are lost altogether.
If you notice any of these signs, you should see us as soon as possible for a complete exam. The sooner we’re able to diagnose gum disease and begin treatment, the less likely it will permanently harm your teeth and gums.

Dental implants are by far the best way to replace missing teeth. But they do more than improve your smile: they can restore your ability to eat, chew and talk properly, especially if the teeth replaced are in the back of your mouth. What’s more, they can improve the entire look of your face by restoring facial height and cheek support lost because of the missing teeth.
There is, however, one obstacle to overcome before receiving dental implants — a lack of sufficient bone at the implant site. Bone loss usually occurs when teeth have been missing for some time. This is because when we chew the forces generated by the teeth stimulate continual bone growth to make up for older bone that has dissolved (resorbed). This stimulation doesn’t occur after teeth are lost, which slows the rate of bone growth. Over time the amount of healthy bone diminishes.
Without enough bone for support, implants can’t be placed properly. Fortunately, some of the bone can be regenerated through techniques that place bone grafting material at the site to stimulate and serve as a scaffold for new bone.Â The new bone will eventually replace the graft.
For missing upper back teeth with bone loss, we can take advantage of facial anatomy to grow the bone needed for implants. This area of the face is where the maxillary sinuses, air spaces lined with a tissue membrane, are located on either side just above the upper jaw. After determining their exact size and location through detailed x-ray imaging, we can surgically access the area inside the mouth just above the missing teeth.
The sinus cavity is an area where bone growth can occur by placing a bone graft between the floor of the sinus and the sinus membrane. Sometimes bone growth enhancers are used to stimulate and speed up regeneration. The procedure can usually be performed with local anesthesia (much like a routine tooth filling), with only mild discomfort afterward for a few days managed by an anti-inflammatory drug like ibuprofen and a decongestant for sinus swelling.
After six to seven months, we re-evaluate the area to see if sufficient bone has returned for implant surgery. If so, you will be well on your way to achieving a new look and better function through dental implants.
