What is a laser dental filling
Definition:
Laser dental filling refers to a restorative procedure in which a dental laser, particularly an erbium laser (Er:YAG or Er,Cr:YSGG), is used for removal of carious tooth structure and/or cavity preparation, followed by restoration with a suitable material, commonly composite resin.
Indications:
Small to moderate dental caries Minimally invasive cavity preparation Pediatric patients with dental anxiety Patients who dislike the noise and vibration of the dental handpiece Selected pit-and-fissure caries Cases where preservation of sound tooth structure is desirable
Longevity:
The laser does not determine how long the filling lasts. Longevity depends mainly on the restorative material, cavity size, bonding technique, moisture control, occlusal forces, oral hygiene and recurrent caries. A composite restoration can last several years, but there is no fixed lifespan specifically attributable to laser preparation.
Advantages:
- Less noise and vibration
- May reduce pain and need for local anesthesia in selected cases
- Conservative tooth preparation
- Useful for improving cooperation in children.
Limitations:
- Not suitable or necessary for every carious lesion
- Treatment may take longer
- Equipment is expensive
- Conventional rotary instruments may still be required in some situations
