Tooth Extraction and Oral Surgery with Medical Conditions: What to Tell Your Dentist Before Chemotherapy, Osteoporosis Drugs, or Blood Thinners

Why am I told to see a dentist first after a cancer diagnosis?

The reason is to clear sources of infection in the mouth before starting chemotherapy or radiation therapy [1]. During chemotherapy, immunity drops and white blood cell counts fall, so cavities, gum inflammation, or damaged teeth that caused no problems before treatment can become a source of infection and complications [1]. Checking for sources of infection and finishing any needed cavity treatment or extractions before treatment therefore helps prevent complications during treatment [1]. When DentStat analyzed 60 patient comments about oral care with medical conditions in oral surgery, the main emotions were the question “why the dentist first after a cancer diagnosis,” fear of complications, and anxiety about preparing before chemotherapy [3].

Can I not have a tooth pulled during chemotherapy or radiation therapy?

Bleeding is not a reason to rule out dental treatment entirely, and in fact getting the mouth in order before treatment is often advised [1]. While treatment is underway, however, timing needs to be coordinated because of lowered immunity and bleeding risk, so the decision is made with your doctors based on blood counts and the treatment schedule [1]. If you have had radiation therapy to the head or neck, a later extraction can be associated with osteoradionecrosis, so you should tell the dentist your treatment history and plan carefully [2]. The standard is coordination between your treating doctor and your dentist rather than your own judgment [1].

I take an osteoporosis drug and my extraction site is not healing. Is it just aging?

When you are taking certain osteoporosis drugs such as bisphosphonates, an extraction site that stays unhealed for a long time is hard to explain as simple aging [2]. Drugs in this class can, in rare cases, be related to medication-related osteonecrosis of the jaw, so bone that is exposed or does not heal several months after an extraction is a sign to have checked [2]. The risk of osteonecrosis varies with the type of drug, how it is given (pills or injections), and how long it has been taken, so telling the dentist your exact medication history is the starting point for planning [2]. Stopping the drug on your own can also affect osteoporosis management, so whether to pause it should be discussed with the prescribing doctor [1].

Can I have a tooth pulled if I take blood thinners or have diabetes?

It is often possible, but telling the dentist your medication and test values in advance and coordinating is a prerequisite [1]. Anticoagulants and antiplatelet drugs thin the blood and can affect bleeding, but stopping them on your own can create greater risks such as blood clots, so whether to pause them is decided by the prescribing doctor and the dentist together [1]. With diabetes, infection and healing can be affected by how well blood sugar is controlled, so the approach is to check your control first and then proceed [1]. In either case, extraction itself is not ruled out; it is treated as a matter of timing and preparation [1].

What should I tell the dentist in advance?

Telling the dentist all your current medications, diagnosed conditions, and treatment history is the core of a safe procedure [1]. In particular, osteoporosis drugs (including pills and injections), anticoagulants and antiplatelet drugs, chemotherapy plans or history, and any history of radiation therapy to the head or neck directly affect plans for surgery or extraction [2]. If you do not know the exact names of your medications, bringing a prescription or medication list helps [1]. With this information, the dentist can coordinate with an internal medicine doctor or general hospital when needed and decide on timing and target values before proceeding [1].

Common myths and facts

Some believe that cancer patients cannot have any dental treatment because they must not bleed, but a dental checkup and extractions before chemotherapy are advised to help prevent complications and are coordinated with your doctors [1]. Some also put down a non-healing extraction site while on osteoporosis drugs to aging, but because medication-related osteonecrosis of the jaw is possible, telling the dentist your medication history matters [2]. On the other hand, the idea that you can never have a tooth pulled while on osteoporosis drugs is also inaccurate; the risk is assessed and a plan is made [2]. Either way, telling the dentist your medications and conditions without leaving anything out is the starting point for any decision [1].
