How much does a dental second opinion cost in California?
Costs vary widely — from free consultations to several hundred dollars — depending on the format. The format you choose matters more than the dentist you see, because it determines whether you pay for chair time, imaging, or just the dentist's analysis. Here is the practical breakdown for California in 2026.
In-person second opinion at a different dental office
An in-person consultation at another California dental office typically costs $75–$200 for the exam, with x-rays adding another $50–$200 if new ones are taken. Most offices waive the consult fee if you commit to treatment with them, which means the price you pay if you do not switch is often the full amount. Insurance may cover part of it; many plans treat the second exam as a routine office visit.
Video / teledentistry consultation
A growing number of California teledentistry services offer 15–30 minute video calls with a licensed dentist. These run $40–$100 per session. The dentist reviews any records you share on screen and gives you a verbal opinion. Some platforms include a written summary; many do not.
Written online second opinion
The newest format — and typically the lowest-friction — is a written opinion delivered asynchronously. You submit photos, x-rays, and a description of the proposed treatment, and a licensed dentist reviews the case and writes back. dentsecond is in this category and charges $29, with follow-up clarifying questions included. The full opinion is delivered in 12–24 hours.
The trade-off is that no one is examining you in person. For diagnostic questions that need a clinical exam (e.g. testing tooth vitality, occlusion analysis), in-person is still the right choice. For interpreting an existing recommendation against the records you already have, written opinions are the most efficient option.
What about insurance?
Most dental insurance plans do not cover online second opinion services like dentsecond. They will sometimes cover an in-person consultation at a different office, especially if your plan considers it a routine exam. FSA and HSA accounts often reimburse dental services regardless of insurance — including a written second opinion — but check with your plan administrator first.
A simple way to choose
If you have records (photos, x-rays, a treatment plan) and just want a professional read on whether the proposed work is reasonable, a written opinion is fastest and cheapest. If you need a fresh diagnostic exam — including new imaging or hands-on tests — an in-person consultation is the right format. Video consultations sit in between and tend to be most useful for general questions about treatment direction.

Is a $29 second opinion legitimate?
Yes — when it is delivered by a US-licensed dentist who reviews the actual records you submit. The price reflects the format (asynchronous, written), not the qualifications of the reviewing dentist.
Can a second opinion be free?
Some dental practices offer free second-opinion consultations as a marketing tool, particularly when they expect to win you as a patient. The honest read is that "free" usually means "promotional"; you should still expect a treatment recommendation that the practice can profit from.
