A dental crown, otherwise known as a cap, covers an infected tooth and can vary in function, depending on the position of the tooth. Crowns cover all the visible parts of a tooth and vary in size, appearance, and functionality.

A crown can be used to protect a weak tooth from breaking, hold together an already broken or worn tooth, cover the tooth with a large filling or dental implant, hold a dental bridge in place, or support a cosmetic modification.

Several types of crowns are available, depending on the tooth to be treated. Stainless-steel crowns are used on permanent teeth, usually as temporary measures in children because they’re more cost-effective for baby teeth that naturally come out over time.

Metal crowns are another option that includes gold alloys, or base-metal alloys. Metal crowns are notable for their ability to withstand biting forces, rarely break or chip, and therefore offer the best results in terms of normal wear and tear.

Porcelain fused to metal crowns most closely resemble a normal tooth and are a good choice for front or back teeth. Other, less common types include all-resin, all-ceramic, all-porcelain, and zirconia crowns.

If you’re getting a crown, you can expect a few things during your visit with Dr. Jenny A. Kanganis. Crown placement usually requires two appointments. The first entails preparation to get an impression of the tooth, shape it, and place a temporary crown. The impression is sent to a lab where a technician makes the crown to be fitted.

During the second appointment, the high-quality porcelain crown is placed on the problematic tooth.

If you notice any signs of discomfort in your mouth, always let Dr. Jenny A. Kanganis know by calling our office. We will determine which type of crown is best for your tooth to give it the added strength it needs. Crowns can be very helpful for your oral health if you have any teeth that need extra support.

Happily for all of us who like to celebrate with friends and family, there’s no need to be Irish to enjoy St. Patrick’s Day. Every March 17^th, many of us take the opportunity to display a bit of Gaelic spirit.

• Green Clothing (it’s tradition!)
• Green Hat (for a jaunty look)
• Green Shamrock (always the perfect accessory)
• Green Hair (for the adventurous among us)
• Green Grins?

Here’s where we draw the line. Emerald Isle? Delightful! Emerald smile? Not so beguiling.

That traditional St. Patrick’s party fare—green-frosted sweet treats and green-colored pastries and green-foamed beers—is full of green-tinted food dyes, which can leave us with teeth in subtle shamrock shades. Luckily, most of us will have only a very temporary tinge to remind us of our dietary shenanigans, and there are simple ways to rid yourself of the green sheen:

• Indulge sparingly in colorful cuisine, and drink water afterwards to rinse away green-dyed foods and beverages.
• Use a straw for green drinks.
• Brush your teeth. (Not only will you brush away the green, but you’ll brush away the sugars from sweet green desserts and the acids from sour green brews.)
• Try a whitening toothpaste.

One special note: if you’ve just whitened your smile, best to eliminate strong food dyes from your diet for a few days. Teeth are more sensitive to staining after whitening, because the whitening process temporarily makes them more porous. Give yourself a few days, and your enamel will be back to (stain)fighting strength.

So, celebrate on the 17^th and feel secure that on the 18^th, your smile won’t be “wearing the green” any longer. But if you find that you’re not happy with the appearance of your smile anytime during the year, if you have more permanent staining caused by natural darkening over time, or workdays fueled by black coffee, or a diet filled with tomato sauce, dark berries, red wine, and other tasty (but discoloring) food, you’re still in luck.

Ask Dr. Jenny A. Kanganis about professional whitening procedures at our Bronxville office for a brighter, more confident smile. And with a bright, confident smile, every day’s a reason to celebrate!

You have probably counted a hundred reasons to stop smoking. It’s unhealthy. It’s expensive. It annoys the people around you. You have to schedule your day around the next cigarette. But here’s reason number 101: Did you know that one of the many side effects of smoking is the damage it does to your smile?

Your Appearance

One of the most obvious results of smoking is the constant yellowing and discoloration of your teeth. Tobacco stains can take longer to remove with home brushing and whitening. And, while a professional cleaning and whitening will make a world of difference, all that good work is undone once you start smoking again.

More important, no smile looks its best with periodontal disease and tooth loss. Smoking has been linked to the presence of more harmful oral bacteria and higher occurrences of cavities and gingivitis (early gum disease). Periodontitis, or severe gum disease, is much more common among smokers. Tooth loss is also much more likely.

Healing after Dental Surgery

Smoking slows the healing process. It has been linked to a weaker immune system, so it’s harder to fight off an infection or to heal from one.  And because of the harmful effect of smoking on bone tissue, there is a higher failure rate for dental implants among smokers. Bone density can be so compromised that an implant is not even an option.

Healing after Extractions

If you have a tooth extracted, the formation of a blood clot at the site of the removal is essential to avoid a condition called dry socket. Dry socket can lead to pain, serious infection, and other complications. Luckily, this clot is resilient and pretty hard to dislodge—unless you apply suction such as sipping through a straw or drawing smoke from a cigarette.

Oral Cancer

Research has shown that smoking is the single most serious risk factor for oral cancer. The good news is that this risk is cut dramatically if you quit!

Let Dr. Jenny A. Kanganis help you maintain your smile. We can offer many more reasons to give up the smoking habit, and we are happy to offer suggestions for quitting during your next visit to our Bronxville office. We want to protect your smile and your health as well. It doesn’t really matter which number on the list finally leads you to quit—every number on that list is your lucky number!

We’re used to seeing athletes wearing mouthguards at practice or play, because dental trauma is one of the most common (and predictable) sports injuries. But it’s not just athletes who are at risk, and there are some events in our daily lives that we just can’t predict. Car accidents, falls, workplace injuries, even innocent playground structures can take their toll on our smiles.

A major chip or a crack in your tooth is upsetting enough, and should be seen by a dentist as soon as possible. It’s even more unnerving when a tooth is knocked out completely. The technical term for a tooth which has been knocked out is an avulsed tooth, and it is a true dental emergency.

If you should suffer a partially or completely dislodged tooth, there is a possibility that your tooth can be reimplanted—if the damage isn’t too severe and if you get to your oral surgeon or dentist immediately.

How can a lost tooth be saved? This is possible because of the complex biological engineering that anchors our teeth within the jaw. The root of a tooth is surrounded by the periodontal ligament. This connective tissue attaches the tooth to the alveolar bone of the jaw. When a tooth is knocked out, this ligament splits apart, leaving some tissue on the tooth root and some within the tooth’s socket.

To successfully reimplant a tooth, the connective tissue cells around the root of the tooth need to be vital, so that they can begin to reattach to the connective tissue left in the socket. Over time, this reattachment is complete, and the tooth becomes firmly anchored to the bone again.

It’s important to protect your tooth before you see us to make sure there will be enough healthy tissue for reattachment. First of all,

• Don’t panic! If you or a friend or family member lose a tooth, call your oral surgeon, your dentist, or your emergency health care provider as soon as possible. You will get specific instructions for your specific situation.

If you are unable to reach your health care provider immediately, there are some general rules for taking care of an avulsed tooth:

• Find the lost tooth. Don’t touch the root—use the crown, or top part of the tooth, to pick it up. You are trying to preserve and protect the connective tissue on the root surface.

• If the tooth is dirty, gently rinse it in milk, saliva, or water. Don’t wipe it off, though. You could damage those connective tissue cells mentioned above.

• Place the tooth back in the socket, if possible. Gently hold it in place with your fingers or bite down (again, gently). You can also place the tooth in your mouth next to your cheek.

• If returning the tooth to the socket is not an option, or if you are worried about a child possibly swallowing the tooth, keep the tooth moist. Whole milk or solutions sold just for the purpose of preserving an avulsed tooth are better choices than water, which damage the tissue cells on the root. And never wrap the tooth tightly—this can also damage the connective tissue.

Above all,

• Don’t delay! The faster a tooth is reimplanted in its socket, the greater chance you have of keeping it. Really, every minute counts. Reimplantations are more successful if they take place within 30 minutes. After an hour out of the mouth, your tooth’s chances of successful reintegration are lower—but still worth pursuing!

What will your oral surgeon do?

• Evaluate the avulsed tooth.

There are variables which can affect whether or not a lost tooth is a good candidate for reimplantation. Trying to replace a baby tooth, for example, could interfere with the formation of the adult tooth. An adult tooth that is broken will probably require a different type of treatment.

• Prevent infection.

You might be given antibiotics and a referral to your doctor for a tetanus booster if needed.

• Clean the site.

The socket will be gently irrigated to clean the area and to remove any clots that may have formed which can interfere with the tooth’s placement.

• Recommend or perform a root canal.

Nerves and blood vessels within the tooth’s pulp generally don’t recover after a serious traumatic injury, so a root canal procedure could be necessary to preserve the health of your tooth. This procedure might be done immediately, or might be recommended for a later date.

• Stabilize your tooth.

The tooth must be stabilized after being reimplanted, so Dr. Jenny Kanganis will use a splint to anchor the tooth to the teeth next to it. The splint can be flexible or rigid, depending on the condition of the alveolar bone. Splinting generally takes from two to eight weeks, and you will be given detailed instructions for taking care of the area while you heal.
