Erbium Dental Laser

By the Dental Nation clinical team — a licensed dental group practising in the UAE

Erbium lasers remove decayed tooth structure and may reduce local anaesthetic use, but cavity preparation usually takes longer.

[1][2]

The short answer

Er:YAG and Er,Cr:YSGG lasers remove caries and prepare cavities as an alternative to conventional rotary instruments.

What is an erbium dental laser?

Erbium laser and conventional options
OptionUse in the reviewed comparison
Er:YAG or Er,Cr:YSGG laserCaries removal and cavity preparation.[1][2]
Rotary instrumentConventional drilling and cavity preparation.[1][2]

[1][2]

How is it used?

Erbium lasers remove decayed tooth structure and prepare a cavity before restoration. The approach has also been studied in pediatric dentistry.

[1][2]
Outcomes reported in the reviews
OutcomeFinding
Local anaesthesiaThe need was reduced in the laser group in one meta-analysis.[1][2]
Operative timeLaser treatment generally took longer than turbine preparation.[1][2]

[1][2]

What are the limits?

Caries removal generally takes longer with an erbium laser than with drilling, making treatment time its clearest reported trade-off.

[1][2]

How does it compare with drilling?

Drilling was faster in the reviewed studies. Erbium treatment reduced local anaesthetic use, while restoration loss, pulpal vitality and postoperative sensitivity showed no significant difference in the meta-analysis.

[1][2]

What might a patient notice?

In studies of children, erbium treatment was associated with less procedural pain, better comfort, lower anxiety indicators and greater acceptance than rotary preparation.

[1][2]

Is it safe?

For up to 12 months, restoration performance was comparable between laser-prepared and bur-prepared cavities, with no consistent laser disadvantage reported.

[1][2]

Frequently asked questions

Does an erbium laser always make a cavity appointment shorter?

No. Caries removal generally took longer with the laser than with drilling.
