Onlay vs. Dental Crown: Which is Better for Your Teeth?

dental_crownsCrowns and onlays are laboratory fabricated restorations that are made to restore and protect teeth that can’t be fixed with fillings, either because there was too much decay or there is too much tooth structure missing. Simply put, fillings have limitations. They just “ fill in” that part of the tooth that Is missing, but they don’t necessarily strengthen or protect the teeth from the forces generated during chewing.

In cases where there has been extensive loss of tooth structure, we often recommend a crown or an onlay, the difference being that an onlay covers just the biting surface of the tooth while the margins of a crown extend all the way to the gum line. Obviously, the crown is a more extensive restoration and involves the removal of more tooth structure. Onlays are typically preferred where the damage to the tooth is more minimal and restoration doesn’t require the removal of as much tooth structure for retention.

Both crowns and onlays can be made of different materials including gold, porcelain fused to various metals and a whole host of tooth colored ceramic materials, depending on the competing needs for strength and esthetics. The goal, of course, is to restore the normal anatomy and esthetics of the tooth so that it can function properly in the mouth.

Either restoration can last for many years if cared for properly. That means practicing excellent oral hygiene and regular visits to the dental office to prevent problems such as tooth decay and gum disease, which can threaten the longevity of any dental restoration.

So, which is best? It just depends on your individual situation. We’ll help you make that decision if the necessity arises. It’s a little like going to the ice cream store- chocolate, vanilla, etc. It’s not that one’s right and the other wrong. You’re still getting your ice cream!

12 Things That Can Harm Your Teeth

HealthySmilesBlogHaving healthy teeth is not only important to your overall appearance but your oral health contributes to your overall well being. Here are 12 things you can avoid to maintain and/or achieve better oral health.

  1. Sugary Foods and Drinks
    Food and drinks that are sugary promote an environment that is conducive to the bacteria that cause tooth decay and gum disease.
  1. Lack of Water
    A dry mouth is the worst environment for decay, allowing the bacteria to multiply and preventing saliva from buffering the acids they make.
  1. Nail Biting
    Habits like nail biting can cause excessive wear and chipping of the front teeth.
  1. Heavy Brushing
    Using anything other than a soft toothbrush will cause erosion and unnecessary wear of the teeth.
  2.  Acidic Foods and Beverages
    Acidic foods and beverages dissolve tooth structure and also promote an environment that promotes the harmful bacteria in the oral cavity.
  1. Neglecting Baby Teeth
    Primary teeth are essential to maintaining the space and relationships needed to ensure proper development and eruption of the permanent teeth.
  1. Using Your Teeth as Tools
    Using your teeth to open bobby pins, beer bottles or to bite string, etc. can chip teeth and cause excessive wear.
  1. Thumb Sucking
    Prolonged thumb sucking beyond the age of 4 can result in a narrow arch form, protrusion of the permanent front teeth and orthodontic problems in general.
  1. Smoking
    Smoking not only is related to oral cancer, but constricts peripheral blood vessels and contributes to periodontal disease.
  1. Chewing Ice
    Chewing ice leads to cold sensitivity and cracked teeth.
  1. Grinding
    Grinding (or bruxism) causes excessive wear, fractured teeth and contributes to jaw joint problems.
  1. Failure to Wear Athletic Guards
    Engaging in contact sports while not wearing the appropriate athletic mouth guard can lead to quite severe traumatic injuries to the teeth including tooth loss.
