Erbium laser in dentistry: what it treats and why it matters for Astana

Key points

• An erbium laser is a tool with a wavelength that water absorbs strongly. Tooth and gum tissue contain water, so the laser can vaporise decay, cut gum tissue and clean surfaces — precisely, without a spinning drill and without heating nearby tissue.
• One device does several jobs: preparing cavities, treating and disinfecting root canals, soft-tissue surgery (frenula, gum contour), treating gums and cleaning the implant surface in peri-implantitis, and removing gum pigmentation.
• The laser does not replace the doctor and does not remove the need for ordinary instruments: the doctor decides what it is used for, and part of the work is still done with instruments.
• Tursunov Clinic has an erbium laser; the doctors trained on it in September 2026, and certificates are on the /sertifikaty page [after upload].
• For Astana this means that procedures patients used to travel to other cities for are now available locally.

How an erbium laser works

Dentistry uses several kinds of laser, and "laser" on its own says nothing. Diode lasers mainly work with soft tissue. Erbium lasers — Er:YAG (2940 nm) and Er,Cr:YSGG (2780 nm) — are the only group that can work with both soft tissue and hard tissue: enamel, dentin, bone.

The reason is the wavelength. Water absorbs it more than almost anything else. A laser pulse hits the tissue, the water inside it flashes to vapour, and a micro-explosion ejects tissue particles — this is called ablation. Healthy enamel holds little water, decayed dentin holds a lot, so the laser removes diseased tissue noticeably faster than healthy tissue. A water spray runs alongside the pulses, so the tissue does not heat up.

That gives it some practical properties:

no drill vibration or whine — for many patients this matters most;

no instrument contact with the tissue, so no bacteria are transferred from the instrument;

the treated surface is clean, without the smear layer a drill leaves behind;

when working on gum tissue, the laser also seals small blood vessels as it goes, and the wound often heals without stitches.

What an erbium laser treats

Below are the uses the clinic has adopted for its laser. Each one notes what the laser does and where its limits are.

Cavities.

The laser vaporises decayed dentin and prepares the cavity for a filling. Because it targets diseased tissue selectively, less healthy enamel is removed than with a drill. In many cases small cavities are treated with less anaesthetic or none at all — but this depends on depth and sensitivity, and "no injection" can never be promised. Limits: the laser does not remove old fillings, metal or ceramic — those need ordinary instruments; deep decay near the nerve needs the same care as with any method.

Root canal disinfection in endodontics.

The main problem in root canal treatment is bacteria in lateral canals and dentinal tubules that neither an instrument nor an irrigating solution can reach. An erbium laser is used to activate irrigation: pulses inside the canal solution create shock waves that drive the antiseptic through the whole canal system and flush out tissue debris. This supplements mechanical instrumentation rather than replacing it. The clinic treats canals under a microscope; laser activation is one more step in that same protocol.

Soft-tissue surgery.

Correcting a tongue-tie or lip-tie, adjusting the gum contour before a restoration or veneers, removing small benign growths of the mucosa, exposing an implant at the second stage. The laser cuts and seals small vessels at the same time: the field stays dry, stitches are often unnecessary, and swelling afterwards is milder. Limits: larger procedures and work involving bone volume are still done with classic methods.

Peri-implantitis.

Peri-implantitis is inflammation of the bone around an implant. The key task in treatment is cleaning the implant's rough surface of bacterial film without damaging it. Metal instruments scratch titanium, while an erbium laser removes biofilm and granulation tissue without touching or heating the surface. This is one of the applications with the strongest evidence for erbium lasers. Limits: the laser is part of the protocol; significant bone loss still needs a bone graft, and sometimes the implant has to be removed.

Gum treatment.

In periodontitis, the laser is used inside periodontal pockets: it removes infected tissue and cleans the root surface. It is used alongside professional cleaning and the Vector device already at the clinic, not instead of them.

Gum pigmentation.

Dark patches on the gum (melanin pigmentation) are a cosmetic issue rather than a medical one, but they bother many patients. The laser removes a thin layer of pigmented mucosa without a scalpel or stitches; healing takes about a week. The pigmentation can partly return over time — the doctor warns about this before the procedure.

Remineralisation and sensitivity.

[Wording is provisional — to confirm with the owner, item 6.] Laser treatment is used to reduce tooth sensitivity and to boost the effectiveness of fluoride treatment per the device manufacturer's protocol. Remineralising therapy is 8,000 ₸ in the clinic's price list; whether a laser stage is included in it is being confirmed.

Why this matters for Astana

An erbium laser is an expensive device, and it cannot be used without training: the settings for enamel, dentin, gum and implant surfaces all differ, and a mistake in the settings means a burn or tissue damage. That is why most clinics do not have one, and where one exists it is often used for only one or two procedures.

Tursunov Clinic has the laser, and in September 2026 the doctors trained in using it [names, course, provider — NEEDS_OWNER]. Certificates are posted on the /sertifikaty page [after upload]. For patients this means laser cavity preparation, laser canal treatment, gum surgery or peri-implantitis treatment are available in Astana, without travelling to Almaty or abroad.

The clinic is equally honest about the other side: the laser is a tool, not a "miracle cure." The doctor determines the indications for it at the exam, and in some cases the classic method will be the better fit.

What a laser appointment looks like

Consultation and examination; a CBCT scan if needed (11,000 ₸). The doctor decides whether the laser is needed in this case.

Protective eyewear for the patient and the doctor is mandatory.

The procedure itself: the patient hears the clicking of the pulses and feels the water; there is no vibration. Anaesthesia is used as needed.

Afterwards: aftercare advice depends on the procedure. After gum surgery there are usually no stitches, and healing takes 5–10 days.

Frequently asked questions

Does the laser hurt?

It feels like less than a drill because there is no vibration or heat, but nothing is 'painless for everyone.' Anaesthesia is given when it is needed.

Can the laser treat everything?

No. Removing old fillings or crowns, major bone surgery and work involving metal are still done with classic methods.

How much does laser treatment cost?

[NEEDS_OWNER — included in the procedure price or charged separately.]

Who at the clinic works with the laser?

[NEEDS_OWNER — list of doctors after training.]

Is the laser safe for an implant?

The erbium laser is — with correct settings it does not heat or scratch titanium, which is exactly why it is used in peri-implantitis.
