Most advice about choosing a dentist comes down to "read the reviews and trust your gut". That is advice for a restaurant. A dentist is a licensed clinician operating under a state board, and almost everything that matters about them is on a public record you are entitled to read.

We hold a listing for all 29,110 licensed dental practices in California, assembled from the federal provider register and the state board’s own licence records. The five checks below are the ones that record makes possible. None of them requires us: you can do every one yourself.

1. The licence, on the board’s own register

Every dentist practising in California holds a licence number issued by the Dental Board of California, and the board publishes a lookup that returns the status, the issue date and any disciplinary action. Of the 29,110 practices we hold, 29,108 carry a licence number we could record — the two that do not are registry entries with a gap, not practices operating without one.

What you are looking for is not just "active". Look at the issue date, which tells you how long they have been licensed in this state, and look for any action on file. A clean record is the common case; the point of checking is that the uncommon case is the one worth knowing about before you are in the chair.

2. Whether the specialty is registered or just advertised

There is a real difference between a dentist who completed a recognised specialty residency and one who takes a weekend course and puts the treatment on the website. Both may do the work well. Only one of them is on the register as a specialist.

California’s registered specialists are far scarcer than the advertising suggests:

Registered dental specialists in California, October 2026

Specialty	Practices	Share of all practices
General practice	26,378	90.6%
Orthodontics	1,544	5.3%
Endodontics (root canals)	858	2.9%
Prosthodontics	395	1.4%
Oral and maxillofacial surgery	177	0.6%
Paediatric dentistry	150	0.5%
Periodontics (gums)	144	0.5%
Oral pathology	74	0.3%
Orofacial pain	23	0.1%

Nine practices in ten are general practice. That is not a criticism — general dentists handle the overwhelming majority of dentistry competently, including a great deal of work that gets advertised as specialist. It does mean that if a practice presents itself as "the implant specialists" you can check in thirty seconds whether that is a registered specialty or a description of what they like doing.

3. One dentist, or a group

The federal register records whether a practice is a sole proprietor, and it is close to an even split: 13,327 of the 29,110 California practices we hold — 46% — are registered as sole proprietors.

Neither is better. They are different experiences, and the register is the only place the distinction is reliably recorded:

• A sole practice usually means the same dentist at every appointment, which matters most for long treatments where continuity of judgement is the thing you are buying.
• A group or corporate practice usually means longer opening hours, more chairs, in-house specialists and cover when someone is away — and a higher chance that the dentist who plans your treatment is not the one who carries it out.
• Neither tells you anything about quality. It tells you what to ask: in a group, ask who will actually be treating you, and ask it before the treatment plan rather than on the day.

4. What they publish about themselves

This one is a proxy, and worth being honest about. Only 7,536 of the 29,110 practices — just under 26% — publish a website at all. We read every one of those we could reach and recorded what was on it. A practice that publishes its opening hours, the treatments it provides and the insurers it accepts is not thereby a better clinician. It is a practice that has decided you should be able to find things out without telephoning, and that attitude tends to survive into the consultation.

The one thing nobody publishes is price. Not one practice in the state publishes a fee, which is why every "average cost" figure you find came from somewhere other than the practices themselves.

5. How the first phone call goes

The last check is the only subjective one, and it is still worth doing deliberately rather than by feel. Ring and ask three things:

1. Who would I be seeing, and are they taking new patients?
2. If I need a treatment plan, do you give it to me itemised and in writing before I commit?
3. What happens if something goes wrong with work you have done — is there a remake policy, and is it written down?

You are not testing their warmth. You are testing whether the answers are specific. "We would have to see you first" is a fine answer to the first question and a poor one to the third.
