Myths about tooth decay

By | Diseases, Preventative | No Comments

Myths often start with a grain of truth, and that’s the case for many of the dental misconceptions most people have absorbed over the years. No matter how educated a person perceives they are concerning dental health, it’s possible a few false impressions have taken root.

Such as…

  • Cavities are a fact of life.
    It’s common knowledge that there are very real, clinically-evidenced explanations for dental health issues, so why is it that many times you cross your fingers and hope luck is on your side when it’s time to take the kids to the dentist? Recent advancements in research have focused a lot of attention on early intervention methods. So with proper education, fluoride, increased access to dental care, and ongoing research, children in this day and age may not need to worry about cavity development. No four-leaf clovers necessary.
  • Sweets are always the culprit
    Ok, ok, you’re aware that eating sweets isn’t doing anything good for our teeth, but focusing too specifically on that one source of sugar just isn’t wise. Here’s why: fighting cavities is essentially about keeping the proper pH balance in your mouth. Maintaining this balance requires adequate saliva flow, a balanced, varied diet, and a sensible daily oral hygiene regimen. Prolonged and frequent exposure to sugar can lower pH levels often enough to seriously impact your dental health, but it’s not just sweets that’s to blame. Fruit and fruit juices, soft drinks, and cooked starches also create that acidic environment which leads to tooth decay.
  • A cavity starts on the inside of your tooth
    This one is several hundred years old, and probably doesn’t affect your concept of tooth decay today. But it’s interesting to think that in the 18th century people believed that “tooth worms” formed within a tooth and ate their way out to the surface. Now we know that dental decay starts from the outside and works its way in, not the other way around!

What can I do about my loose denture?

By | Treatment information | No Comments

Lower dentures to replace missing teeth are normally the more difficult denture for people to get used to. Here are 3 of the main reasons they are often loose and uncomfortable.

  1. Your tongue is one of the strongest muscles in the body. It can easily flick a lower denture around.
  2. A lower denture only has a thin horseshoe shaped area of gum to sit on (unlike an upper denture which can rest on almost the whole surface area of your upper jaw & palate and also has suction). The lips are pushing the lower denture backwards and your tongue is pushing it forwards and lifting it.
  3. An older denture may not fit as snugly as when it was first made. Over time the jaw bone resorbs (or shrinks). This resorption happens the most during the first 6 months after a tooth has been removed but continues at a slower rate for the rest of your life.

Loose lower dentures – 5 potential solutions

  1. If you have an old denture that used to be comfortable and that you are happy with, appearance wise, but has become loose, an option may be to reline the fitting surface. This means putting a new layer of acrylic (pink plastic) on the fitting surface of the denture. This fills up any gaps between the denture and the gum and may help to re-stabilise it.
  2. Making a basic new acrylic denture.
  3. If there are teeth present making a cobalt chrome denture with clasps that clip around the remaining teeth to assist grip.
  4. If there are teeth present placing dental crowns on teeth adjacent to the denture with special precision attachments which the denture snugly clips onto. Special attachment crowns which also have milled parallel walls make for a very satisfactory solution – a secure denture and no visible clasps.
  5. Retaining the denture with dental implants.
