What are dental crowns?

April 23rd, 2019

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.

Headaches, TMJ, and Dentistry

April 16th, 2019

That ache in your head may stem from your jaw. If your jaw falls out of alignment, you could have temporomandibular joint disorder, or TMD.

It's not clear what causes TMD. Obesity may factor in. Stress and pressure on the jaw may also contribute. A misaligned bite (that is, where your upper and lower teeth don't fit together when you close your mouth) may cause TMD symptoms, too.

TMD can affect your life and your health by making it painful to eat and hard to sleep. Some people find the nagging pain difficult to bear.

Symptoms of TMD include:

  • Recurring headaches with no other cause
  • Pain along and behind your ears
  • Pain in your cheeks or lower face
  • Clicking noises when you talk or chew
  • Tired or sore jaw muscles after eating
  • Limited jaw movement

If you experience the symptoms listed here, make an appointment with our office. We’ll take an X-ray to look at your bite, and determine if TMD could be the culprit. If you have TMD we can offer a number of treatments, including:

  • Relaxation and stress reduction techniques
  • Pain reduction recommendations, which might involve visualization or medication
  • Jaw joint exercises that can help reduce stress and improve your alignment

Left untreated, TMD headaches and other symptoms can become quite severe. If you suffer the symptoms of TMD, you do not have to live in pain. Make an appointment at our Kingston, ON office to learn how we can reduce your pain and restore comfort to your life.

What are Sealants?

April 9th, 2019

Sealants offer many benefits, but the best is their ability to protect your molars. Molars are full of small caverns that can be the perfect breeding ground for tooth decay and plaque buildup.

Use of protective sealants prevents this buildup from happening. Although children often receive sealants for routine preventive care, they aren’t the only ones who can benefit from this treatment. Sealants can also help adults who have deep canyons or grooves in their teeth.

They are commonly placed on the rear molars that tend to suffer the most decay. Because your molars are used substantially as grinding surfaces, food is more likely to be trapped among them.

Sealant solution consists a composite material that contains bonding agents that seal the top of your teeth. The process is quick and painless, which makes it a great solution for both children and adults who have had trouble with cavities and tooth decay. Sealants also last for several years, and repair is a simple process that can be completed by Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough.

The process of putting sealants on teeth starts with the tooth getting cleaned. We clean it with a type of baking soda spray called sodium bicarbonate. Then acid is etched onto the teeth to rough up the surface.

We apply an alcohol-based liquid to dry the area where the sealant is supposed to go. After it completely covers the surface of the treated teeth, the sealant is cured with a light that makes it hard and long-lasting.

Getting sealants can prevent the possible restorative costs that come from cavities. Sealants help to protect your tooth’s enamel from harmful acids and prevent decay, which can be an investment in itself. The whole process is quick, so it should be easy to schedule an appointment at Cataraqui Dental Centre.

Periodontics and Pregnancy

April 2nd, 2019

Periodontal health — which refers to the condition of the structures that support your teeth — is an important part of your oral and overall health. However, periodontal health becomes even more important when you're pregnant. Bad oral health can have detrimental effects on the health of your unborn child and can lead to low-birth weight babies and giving birth to a pre-term baby, according to reports by the American Academy of Periodontology (AAP), the European Federation of Periodontology (EFP), and several research studies.

Periodontal disease (gum disease) is a set of chronic, bacteria-induced, inflammatory diseases that attack the gum tissue and in more severe cases, the bones supporting the teeth. Early signs of periodontal disease usually include tenderness, swelling, and redness. Symptoms can also include bleeding gums when flossing or brushing, receding gums, loose teeth, and bad breath. These signs shouldn't be ignored, especially if you're pregnant.

Prevention is the best tool you have to fight periodontal disease. Here are some steps you can take to keep your gums in tiptop shape:

  • Brush your teeth properly twice a day – angle your toothbrush at the gum line to help disrupt the bacterial growth that eventually leads to periodontal disease, and make sure you don't brush too hard.
  • Floss daily and clean behind the back molars on the top and bottom of your mouth.
  • Use antiseptic mouthwash to rid your mouth of the bacteria that can cause gum disease.
  • Get regular checkups at our Kingston, ON office to ensure you have no signs of periodontal disease and that your oral hygiene habits are effective.

Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough and our team urge women to care for their periodontal health during pregnancy to avoid complications. If you have any questions regarding periodontal health and how it affects you and your baby's overall health, please contact our Kingston, ON office for more information.
