Science for Your Smile

You may have heard of dentists using lasers to treat soft tissue problems. But have you ever heard of a laser being used to numb teeth? Ours can – and much more!

The laser our Growing Great Grins doctors use is extremely versatile. Because it can be used at varying settings, it can work on soft tissue like your gums, frenums, and the pulp, and hard tissue like your teeth. This means we can use it for fixing cavities and also for soft tissue procedures like frenectomies or gum contouring. But the very best thing lasers let us do is avoiding analgesic shots. That’s right! With lasers, we can almost always eliminate Novocain.

So how is that better than a Novocain shot?

The truth is, to lots of children, the SHOT is the worst part of the dental experience, even though it is the thing that ultimately stops the pain. It causes stress and sometimes, just the anticipation of the shot makes dentistry an anxiety-filled experience. Plus, it feels weird! Now, with the laser, what used to be miserable becomes an adventure!

Here’s how it works:

• Your child will be seated in one of our comfortable dental chairs. If they need a little extra comfort they can choose a stuffed friend, a cushion to sit on, a blanket, or a neck support pillow.
• Next, they pick the movie or TV show that will most entertain them.
• Then they will pick the smell they would like in their nose (if your family opts to use nitrous oxide to further help them relax).
• After they pick their smell, we show your child exactly how the laser sounds and works so it will not be a surprise to them.
• Finally, it is the dentist’s turn to play!

How Lasers Work

Lasers may sound like a fantasy but there is no wizardry involved. It’s all physics!

Let’s get technical: Lasers use a light frequency of 2780 nM. At this frequency, energy photons are
1. attracted to water and
2. hydroxyapatite, the organic matrix of tooth structure.

This natural attraction allows us to set the laser to deliver controlled bursts of photons to several possible places:

• To the water in the soft tissue to cause tissue removal
• Down the crystal matrix of the teeth to affect the pulp resulting in laser analgesia
• Directly focused on the organic crystal matrix of the tooth to cause hard tissue removal

Additionally, it may also have other biochemical effects which can promote the health of the tooth

Even if you didn’t understand all of that, it’s pretty clear that lasers make dental care much better for kids of all ages and stages.
