Fillings with Sydney Laser Dentistry
Most people associate dentistry with fillings. Fillings should be prepared with long term health of the tooth in mind. To do this we must remove only diseased tissue or decay leaving the surrounding good tooth structure intact and substantially decontaminated. The finished tooth surface must also be amenable to good bonding to a filling material.
With these criteria in mind, the laser becomes the perfect tool. We get to differentially separate good from bad tooth structure, using a laser thereby keeping tooth reduction to a minimum. The laser will seek out and destroy almost all bacteria in the cavity and will leave a pristine surface for bonding, unlike a drill which leaves contaminated smear layers on the surface.
The preparation of dental decay with laser affects the tooth less also because it cool at the surface, drills act by friction and no matter how much water is used to cool, heating of the tooth and therefore inflammation of the pulp will occur. On the other hand lasers do not create any mechanical contact with the tooth therefore any heating is at atomic levels and the actual surface is cooler . When we look at the microscope of teeth prepared by laser and those prepared by drilling, we see a lot of inflammation cells when we drilled and no change in the pulp of a lasered tooth.
Lasers are used to prepare dental cavities to receive fillings very well. The advantages to preparing with laser are as follows:
- Less Pain, in fact 75% of the time we do not need
injections to prepare a tooth.
- Smaller Preparations, at Sydney Laser Dentistry we are
“minimally invasive dentists” which means we are extremely
conservative with what nature has provided for you.
- Better Bonding, nobody wants those old amalgam fillings anymore! By preparing with laser, the dentist at Sydney Laser Dentistry can provide a better, cleaner surface to bond modern dental adhesives to your tooth, this means a great quality finish for you.
