Good clinical evidence of efficacy for a range of dental conditions

Treatment outcomes found to be effective leading to:

• Reduction in pain.

• Reduction in inflammation and trismus.

• Improvement in wound healing.


Dentine hypersensitivity

• Significantly better pain reduction for LLLT as a monotherapy compared to placebo¹

• “Superior” outcomes compared to topical desensitising agents²


Surgical removal of impacted third molars

• Moderate benefit for trismus compared to controls (average of 4.2 mm on the second day and 5.2 mm on the seventh

day after surgery) when used as adjunct therapy.³


Oral mucositis

• Can help prevent development of oral mucositis and significantly reduce pain, severity and duration of symptoms⁴

• “Moderate-to-strong evidence in favour of LLLT … as a well- tolerated, relatively inexpensive intervention”


Orofacial neuralgia

 • “Low-level lasers [LLLT] have been shown to be effective in improving oral and maxillofacial pain,” in particular

pain due to trigeminal neuralgia and post-herpetic neuralgia.⁶



• “Submucosal debridement with adjunctive local delivery of…laser treatment may reduce clinical signs of

peri-implant mucosal inflammation to a greater extent relative to submucosal debridement using curettes

with adjunctive irrigation with chlorhexidine.”


Orthodontic pain

• Significant pain reduction and faster pain relief using LLLT during placement of orthodontic appliances

compared to placebo ⁶,, , ¹⁰

• Reductions in prostaglandin-E(2) (PGE(2) levels, a pro-inflammatory mediator ¹⁰



• Significantly improved wound healing in patients following gingivetcomy operations¹¹, ¹²


Cavity preparation

• Decreased pain in children after receiving LLLT treatment before cavity preparation¹³



• Significant improvements in gingival inflammation¹⁴, ¹⁵



• As an adjunct therapy, significantly reduced pain one day post-surgery¹⁶


TMJ pain

• Significant improvements in pain and movement¹⁷, ¹⁸
