Why your gums may bleed more during a cleaning 

Blood thinners help prevent harmful clots. Some slow the clotting process, while others keep platelets from clumping together. MedlinePlus says bleeding is the most common side effect of these medicines.¹ 

Your gums may also play a role. The National Institute of Dental and Craniofacial Research says plaque and tartar can inflame the gums, and gums affected by gum disease may bleed easily.² So the blood thinner may not be the only reason your gums bleed during a cleaning. 

Do you need to stop your blood thinner before a cleaning? 

Usually not. According to the American Dental Association (ADA), most patients do not need to change anticoagulant or antiplatelet therapy before dental care.³ Stopping or reducing these medicines can raise the risk of a blood clot, stroke or heart attack. 

Do not stop or change your dose unless the clinician who prescribed it tells you to. Always tell your dental provider which medicines and supplements you take. 

If there is a concern about your specific case, your dental provider may speak with your prescribing clinician so they can plan your care together. 

What bleeding during a cleaning actually looks like 

The ADA summarizes research that treated cleaning above the gumline as a low-risk dental procedure. In people taking newer direct-acting blood thinners, bleeding rates were low. When bleeding happened, it was usually mild and controlled with local measures.³ 

Your care team may use pressure or another local treatment to control bleeding in the office. 

Signs that warrant a call to your doctor 

MedlinePlus says to call your healthcare provider if bleeding from your gums does not stop quickly or if you notice other signs of serious bleeding, such as:¹ 

• Unusual bruising 

• Red or brown urine 

• Red or black stools 

• Dizziness or weakness 

Contact your dental provider or prescribing clinician if you are concerned about bleeding after your cleaning. 

How to prepare for your cleaning 

A little planning can help your visit go smoothly. Here are some steps to take before you go: 

• Tell your dental team about every medicine you take, including blood thinners. 

• Do not skip or change your dose without your doctor's approval. 

• Let the office know if your medicine or dose has changed recently. 

• Ask your dental provider if there is anything specific to watch for afterward. 

Even small changes are worth mentioning; make sure your dental provider is kept up to date so they can plan your visit accordingly.  

Blood thinners: Is bleeding after a cleaning an emergency? FAQs 

Still have questions about blood thinners and dental cleanings? These answers cover a few common concerns. 

Will the dental provider cancel my cleaning if I'm on blood thinners? 

Not because of the blood thinner alone. Your dental provider will review your health history first. For most patients, a routine cleaning can go ahead as planned. If your case is more complex, they may speak with your doctor first. 

Should I tell my dental provider which blood thinner I take? 

Yes. The type and dose of blood thinner matters. Different medications work in different ways. Your care team uses that information to plan your visit safely. 

Can regular cleanings help reduce gum bleeding over time? 

Regular cleanings remove tartar that brushing and flossing cannot. Your dental provider can check whether gum disease is adding to the bleeding and tell you how often you need a cleaning. 

What if I forget to mention my blood thinner before my visit? 

Tell your care team as soon as you remember, even if it is right before the cleaning starts. They can adjust their approach. It is never too late to share that information.
