Dental Mouth Mirrors Explained: Plane, Rhodium & Photographic

Why the mouth mirror matters

The mouth mirror is one of the most-used instruments in dentistry. It provides indirect vision of surfaces the clinician cannot see directly, reflects light into the mouth, and retracts the cheek or tongue. A good mirror gives a bright, clear, distortion-free image — which makes diagnosis and treatment easier.

Plane vs concave heads

A plane (flat) mirror gives a true, life-size reflection and is the everyday choice for examination and most procedures. A concave mirror magnifies the image, which can help with fine detail, but it shows a slightly curved field. Most clinicians keep plane mirrors as their standard and reach for magnification when needed.

Front-surface and rhodium-coated mirrors

On an ordinary “back-surface” mirror the reflective layer sits behind the glass, which creates a faint double image (ghosting). Front-surface mirrors place the reflective coating on the front of the glass, removing the ghost image for a sharp, single reflection. Rhodium is a hard, bright, corrosion-resistant metal often used for this coating, giving excellent clarity and a long service life.

Intraoral photographic mirrors

Photographic mirrors are larger, highly polished mirrors used to capture occlusal, buccal and lingual views for clinical records and case presentation. They come in adult and child sizes and in shapes matched to each view, and are usually double-sided.

Sizes and care

Mirror heads come in a range of numbered sizes; sizes 4 and 5 are common for adults. To keep mirrors clear, avoid touching the reflective surface, clean gently to prevent scratches, and replace any mirror that becomes marked or pitted. Handles are typically hollow stainless steel and accept standard screw-in mirror heads.
