A dental crown is often called a “cap.” A dental crown covers all of the visible parts of the tooth and has many functions and reasons for placement.

There are several different types of crowns available at Cataraqui Dental Centre. They vary in their material, appearance, and functionality. A PFM, or porcelain fused to high-noble metal, is the most common. A full cast, high noble metal crown is a gold crown, and a stainless-steel crown is meant to be temporary. The most natural-looking crown is one that is all porcelain. These are often used for front teeth.

Getting a crown typically requires two appointments. The first is a preparation with impressions, shaping, and placing a temporary. The impressions are either sent to a dental lab, where the process generally takes two weeks, or done in-office with a machine that can make a crown without needing a second appointment. These crowns are made from a high-quality solid block of porcelain. The shape of the tooth is constructed from a digital 3D image of your tooth.

To accurately determine which type of crown is best, you must first know why you need the crown and in what area of your mouth is it needed, which can be answered when you visit us at Cataraqui Dental Centre. For instance, if you have a gold crown on the lower right and need a new crown directly above on the upper right, the best durability and long-lasting relationship is another gold crown.

If you need a crown on a front tooth, a gold crown may not be the best choice. A PFM has strength but is not ideal, as a dark line will appear at the gum line. A full porcelain crown is going to look as close to a natural tooth as possible, but will have less strength than a gold crown.

There are two types of porcelain crowns, depending on how they are made. A dental lab makes a full porcelain crown by baking layer upon layer to make the porcelain look like natural enamel. A full porcelain crown made in-office out of a solid piece of porcelain will have increased strength. However, the natural layered appearance is extremely difficult to achieve.

A crown is placed on a tooth when added strength is needed. Cracks, large broken-down fillings, or previous root canal treatment are all conditions where a crown is the standard care. The type of crown that is most appropriate depends greatly on location.

Congratulations! Your child is beginning to leave her bottle behind and has started to use her first sippy cup. And the best training cup is one that makes the transition from bottle to cup an efficient, timely, and healthy one.

The Right Training Cup

While a “no spill” cup seems like the perfect choice for toddler and parent alike, those cups are designed much like baby bottles. The same valve in the no-spill top that keeps the liquid from spilling requires your child to suck rather than sip to get a drink. If your child’s cup has a top with a spout, she will learn to sip from it. Two handles and a weighted base make spills less likely.

When to Use a Training Cup

Children can be introduced to a sippy cup before they are one year old, and we suggest phasing out the bottle between the ages of 12 and 24 months. Use a sippy cup as the source for all liquids at that age, and only when your child is thirsty and at mealtime to avoid overdrinking. The transition from sippy cup to regular cup should be a swift one.

Healthy Sipping Habits

The best first option in a sippy cup between meals is water. Milk or juice should be offered at mealtimes, when saliva production increases and helps neutralize the effects of these drinks on young teeth. And don’t let your child go to sleep with anything other than water—falling asleep with a cup filled with milk, juice, or other sugary drinks means these liquids stay in the mouth overnight. Finally, while a sippy cup is convenient and portable, don’t let your young child walk and sip at the same time to avoid injuries.

When your child comes to our Kingston, ON office for her first visit, please bring any questions you might have about training cups. We would be glad to share ways to make the move from bottle to cup both successful and safe!

Dental problems do not always wait for normal office hours. Broken fillings or damaged teeth are common reasons for emergency treatment. Toothaches and abscesses can also require prompt attention. Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough can provide you with the information and treatment you need to prevent the problem from becoming worse. Emergency dental care is only a phone call away, 24 hours a day, seven days a week.

Abscess

An abscess is a bacterial infection, and will normally cause pain and swelling around the affected tooth and gum area. Antibiotics are not always necessary, but you should seek treatment quickly. Left untreated, an infection can spread and cause serious complications.

Toothache

There are many reasons that you may develop a sudden toothache. The cause of the pain may be a particle of food lodged between your tooth and gum line. One of the first steps you can take is to rinse your mouth with warm water. You may also try gently flossing the area to dislodge the particle. Do not continue flossing if bleeding occurs.

Toothaches can occur from a carie — a cavity in the tooth — or from a fracture. Sensitivity to heat or cold may also cause tooth pain. You should make an appointment to ensure that a minor problem does not become serious. We may recommend acetaminophen or another pain reliever to reduce the pain before your visit.

Additional tips and treatments:

• If you have fractured a tooth, rinse the area with warm water to keep the surfaces clean. Apply a cold compress to the outside of your facial area to reduce swelling.
• A tooth that has been knocked out should be kept moist, in a clean container, until you can receive treatment.
• Do not apply aspirin directly on a damaged tooth or gum area as it can cause tissue irritation.
• If you suspect that your jaw has been broken, go to an emergency room immediately.
• If you have bitten or damaged your lips or tongue, rinse your mouth well with warm water. If bleeding continues, call us or seek other medical attention immediately.

Our team at Cataraqui Dental Centre is ready to assist you when you have an emergency dental need. When you call, please provide us with as much information as possible so we can offer recommendations that will assist you until your appointment. Do not delay; emergency treatment is available and immediate treatment is the best course of action.

Have you ever wondered why people have wisdom teeth? These are a third set of molars that come in behind the rest of all your other teeth, usually during early adulthood. Scientists and anthropologists believe that wisdom teeth are a result of evolution, because our ancestors needed these extra teeth to handle their primitive diets. Nowadays, the average diet consists of fewer hard-to-chew foods, which renders wisdom teeth largely superfluous.

Most people begin to experience wisdom teeth pain between the ages of 17 and 25. Our ancestors nicknamed them wisdom teeth because they appeared at a time in life when we supposedly grew wiser.

If you’ve already had your wisdom teeth removed, you know how painful they can become if they aren’t taken care of promptly. If not, watch out for discomfort in the back of your mouth and let Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough know right away if you think your wisdom teeth are coming in.

In some cases, people do not experience any problems or discomfort with their wisdom teeth. These patients may keep their wisdom teeth intact if there’s enough room in their jaw to fit them properly. But this is generally not the case, so wisdom teeth can cause several concerns, depending on which direction they grow.

Common problems include:

• Damage to surrounding teeth due to the pressure from the emerging teeth
• Infection that causes the surrounding gums to swell and become painful
• Tooth decay due to the lack of room to clean the teeth properly
• Impaction (when the tooth is unable to break through the skin)
• A cyst that may damage the jaw, the surrounding teeth, and nerves

If you haven’t had your wisdom teeth removed yet, there are many symptoms to watch out for when they begin to grow. Symptoms may include:

• Pain or stiffness in the jaw
• Tooth irritation
• Swelling of gum tissue
• Crowding of other teeth
• Spread of tooth decay or gum disease on nearby teeth

If you’ve noticed these symptoms, schedule an appointment at our Kingston, ON office. Don’t forget: This is a common procedure that will take some time to recover from. Allow your mouth to heal, and then you’ll be able to get back to a normal routine quickly and be free from pain!
