Dental Lasers

In recent years, lasers have become a helpful tool in several areas of dentistry.   In some ways lasers are a victim of their own hype: advertisers have made claims about dental lasers that just aren’t realistic.   But used appropriately, they can assist us in providing better care in some areas.   We employ several different types of lasers to accomplish different things.

A laser will deliver energy to a target tissue in the form of light.  Depending on the intended result, we will use different lasers and different wavelengths.   In dentistry, these targets can be soft tissue, decayed tooth structure, infected tooth/bone, disinfecting chemicals, or whitening enhancers.   Each one absorbs a different wavelength of light while reflecting others.

Soft tissue procedures
If we have to cut soft tissue, for example to let a tooth grow in easier or free up a tongue-tied child, a laser can be a way to do so with almost no bleeding, and very little post-operative pain or swelling.   

Restorative procedures
Certain lasers can be used to aid in cleaning decay out of teeth, and killing off any bacteria still inside the tooth structure.   In some applications they can be used to cure the tooth-coloured filling materials we use.

Tooth whitening
In some in-office whitening procedures, we can activate the whitening chemical with a special light or laser to speed up the process.

Treating gum disease
Certain lasers can be useful in killing bacteria in infected pockets around the teeth, particularly when combined with specific, laser-activated antibacterial chemicals.  This process is called photodynamic disinfection or PDD.   Lasers can also stimulate reattachment of gums tissue in some cases.

Whenever you are in to see us and we make you wear the special sunglasses, you’ll know we are using a laser of some kind.   Please ask and well be glad to explain how we are using it as part of your treatment.
