If you suffered an injury due to negligent dental treatment, you may be able to sue your dentist and seek compensation for your medical expenses, corrective procedures, lost wages, and pain and suffering. Understanding how to sue a dentist in California starts with gathering evidence, determining whether malpractice occurred, and following the state’s legal requirements.

To pursue a dental malpractice claim, you should:

  1. Collect your dental records: Gather treatment records, X-rays, bills, photographs, and documents showing the injuries you experienced.
  2. Document your injuries and financial losses: Keep records of additional treatments, medical expenses, missed work, and ongoing symptoms.
  3. Consult a dental malpractice attorney: An attorney can evaluate whether your dentist failed to meet the accepted standard of care and whether that failure caused your injuries.
  4. Obtain an expert evaluation: Dental malpractice cases generally require expert testimony to establish the appropriate standard of care and how the dentist’s actions caused harm.
  5. Provide the required legal notice: California generally requires at least 90 days’ written notice before filing a professional negligence lawsuit against a healthcare provider.
  6. File your dental malpractice lawsuit: If your claim has a legal basis and the applicable requirements are satisfied, your attorney can help initiate legal proceedings.

How long do you have to sue a dentist in California?

California generally requires dental malpractice lawsuits to be filed within one year of discovering the injury, or three years from the date of injury, whichever occurs first. Certain exceptions and extensions may apply.

If you believe your dentist caused preventable injuries, speaking with a dental malpractice attorney as soon as possible can help you understand your rights, preserve important evidence, and determine your next steps.

Key Takeaways

  • Your dental records are yours to obtain. A dentist must permit inspection within five working days of a request and provide copies within fifteen days.
  • Copying charges are capped by statute at twenty-five cents a page for paper copies.
  • Someone qualified has to review the records before anyone can say whether there is a claim. The California Courts state that an expert witness is almost always needed.
  • A written notice must be served on the provider at least 90 days before suing, and there is no court form for it.
  • None of this stops the filing deadline from running, and that deadline is the earliest of two periods rather than the later one.

Step One: Get the Records

Nothing useful can be assessed without them, and the right to them does not depend on anyone’s goodwill.

The Dental Board of California states that “the dentist is required to provide you with a copy of the records,” citing Health and Safety Code section 123110, and advises that a written request is recommended.

That statute sets the timeframes. A provider must permit a patient to inspect records “during business hours within five working days after receipt of the request,” and copies must be “transmitted within 15 days after receiving the request.” Charges are limited: the statute caps paper copies at “twenty-five cents ($0.25) per page,” and fifty cents a page for records copied from microfilm.

Three practical points follow. Put the request in writing, because the timeframes run from receipt of a request and a written one is provable. Ask for the complete file rather than a summary — notes, charts, treatment plans, consent documentation and imaging. And make the request early, because the clock described further down this page does not pause while you wait.

Step Two: Someone Qualified Has to Review Them

A dental malpractice claim is not established by a poor result. It is established by showing that the care fell below the standard a competent practitioner would have met, and that this caused the harm. Our page on California dental malpractice claims sets out what has to be proved.

What the records make possible is an assessment of that question by someone qualified to make it. The California Courts’ guidance on suing a healthcare provider is direct about why: “If you’re suing about the care or treatment you received, you almost always need an expert witness,” because “you need an expert to say what the standards are” and that the provider did not meet them.

The same guidance adds a warning that belongs in any honest account of this process. “Expert witnesses are usually very expensive,” and if you win, “you only get these fees back if it was properly set up and the judge orders it.” Recovery of expert costs is conditional, not automatic.

This step is also the one that answers the question most people actually have, which is not how to sue but whether there is anything to sue about.

Step Three: The Notice Before Filing

California requires advance written notice before a healthcare provider can be sued, and this is the prerequisite most often discovered too late.

The Courts state the rule plainly: “Before you can sue you must let them know in writing at least 90 days before you sue.” The notice must tell the provider three things — “the legal reason you’re suing,” “what your injuries are,” and “what losses you have.”

Two features of it cause trouble. First, as the Courts put it, “there is not a court form to use.” There is no template to fill in, which means the notice has to be drafted. Second, “you must serve the notice on the provider following specific rules” — service is formal, and getting it wrong is not a clerical problem.

Ninety days is also not a short period when a deadline is approaching. A notice served late in the limitation period interacts with that deadline in a way that needs to be worked out rather than assumed, and it is a question to put to someone before relying on an answer either way.

The Clock Running Underneath All of It

The deadline for suing a healthcare provider is not the two-year period that applies to ordinary injury claims, and it is not the later of two dates. It is the earlier.

The Courts state that you must file “by the earliest of either” one year after you found out about, or should have found out about, the injury, or three years from the date of the injury. They also note exceptions, including where something was left inside a patient and where the injured person was six or younger.

Our dental malpractice page sets out how those periods operate. The reason they appear here is sequencing: obtaining records takes days to weeks, review takes longer, and the notice adds ninety days before a complaint can be filed. Those steps have to fit inside a window that may already be partly spent.

What Is Not a Prerequisite

Several things commonly described as steps are not required before filing.

A complaint to the Dental Board. Nothing requires one before a claim is brought, and it does not substitute for one. The Board states that “refunds or monetary compensation are beyond the authority of the Board” and that “any action taken by the Board has no impact on the civil remedies that may be available to you.” The two run independently, in either order or neither.

Dealing with the provider’s insurer. There is no obligation to give the other side’s insurer a recorded statement, or to do so on their schedule.

Reaching a view on what the claim is worth. That cannot be done before the records have been reviewed, and it is not something that has to be settled in order to take the steps above.

Frequently Asked Questions

Filing comes last. Before a complaint can properly be filed you need the dental records, a qualified review establishing that the care fell below the standard and caused the harm, and a written notice served on the provider at least 90 days beforehand. All of that has to happen inside a filing deadline that is already running.

Request them, preferably in writing. The Dental Board of California states that a dentist is required to provide a copy of the records, citing Health and Safety Code section 123110. Under that section a provider must permit inspection within five working days of the request and transmit copies within fifteen days.

Yes, within limits. The statute caps paper copies at twenty-five cents per page, and fifty cents per page for records copied from microfilm.

Yes. The California Courts state that you must let the provider know in writing at least 90 days before suing, and that the notice must set out the legal reason for the claim, the injuries, and the losses. There is no court form, and the notice must be served following specific rules.

It is the earliest of one year after you discovered or should have discovered the injury, or three years from the date of injury, with some exceptions. It is the earlier of the two rather than the later, which is what catches people out.

Almost always. The California Courts state that an expert is needed to establish what the standards are and that the provider did not meet them. They also note that experts are usually very expensive and that their fees are recoverable only if the case is properly set up and the judge orders it.

It is not a prerequisite and it is not a way to obtain money. The Board states that monetary compensation is beyond its authority and that its action has no impact on civil remedies. The two are separate processes.
