Should I stop blood thinners before gum surgery?

Most patients keep taking blood thinners for gum and implant surgery. The ADA reports strong evidence that warfarin and antiplatelet drugs should not be altered before dental procedures, and limited evidence that most patients on the newer direct oral anticoagulants need no change.

Any change is made with the prescribing physician; the ADA states that changes should follow the physician's advice.
For higher-risk patients on apixaban, rivaroxaban, dabigatran or edoxaban, the ADA lists options decided with the physician, including a pause of 24 to 48 hours.
After a heart stent, antiplatelet drugs should not be stopped early, and the cardiologist is consulted first.
Bleeding is controlled with local measures such as pressure, hemostatic agents and stitches.

Bone drugs follow the same rule. The ADA reports that stopping bisphosphonates may not remove the risk of osteonecrosis of the jaw. Do not stop any medicine without the prescribing physician. The medication review at the first visit.

Do I need antibiotics before gum surgery?

Antibiotics before gum surgery are for patients with specific heart conditions and for some joint-replacement cases chosen with the orthopedic surgeon. For joints, the ADA's 2015 guideline states: "In general, for patients with prosthetic joint implants, prophylactic antibiotics are not recommended prior to dental procedures to prevent prosthetic joint infection."

The American Heart Association, with ADA input, recommends premedication against infective endocarditis for the highest-risk groups:

Prosthetic heart valves, including transcatheter valves, or prosthetic material used to repair a valve.
A past case of infective endocarditis.
A heart transplant with valve regurgitation from a structurally abnormal valve.
Certain congenital heart disease, such as unrepaired cyanotic disease.

For these patients, premedication covers dental procedures that manipulate gum tissue or perforate the lining of the mouth, which includes gum and implant surgery. The AHA's 2021 scientific statement recommended no changes to the earlier guidelines. Does gum surgery hurt?

What should I do the day before surgery?

The day before surgery, confirm the fasting plan, the ride home and the medication schedule with the office.

Clear liquids are allowed until 2 hours before sedation, per the ASA table.
A light meal is allowed until 6 hours before sedation.
Tell the office about GLP-1 drugs; the ADA guidelines call for modified fasting with drugs that slow stomach emptying.
Without sedation, Cleveland Clinic advises eating a good meal before osseous surgery, since the mouth will be tender afterward.
Arrange a driver for any sedation; Cleveland Clinic says no ride is needed for local anesthesia or nitrous oxide alone.
Skip smoking and alcohol for 24 hours before and after surgery, per Cleveland Clinic.
Plan for an adult to stay the first 24 hours after sedation, as the ASA suggests.
Wear loose, comfortable clothing, as the ASA advises.
Ask which regular medicines to take that morning.

Sedation and fasting.

What should I buy before gum surgery?

Buy soft foods, ice packs, gauze and the pain relievers the surgeon approves, and fill prescriptions before the surgery day.

Soft, cool foods for the first day: yogurt, pudding and smoothies, per Cleveland Clinic's gum graft guidance.
Soft foods for the first week: eggs, pasta, fish and cooked vegetables.
Ice packs for the outer jaw to reduce swelling.
Gauze: a folded piece pressed on an extraction site for 15 minutes controls oozing, per Cleveland Clinic.
An antibacterial mouthwash, if the surgeon recommends one, to keep the area clean.
Over-the-counter pain relievers the surgeon approves, plus any prescribed medicines.
An extra pillow, since Cleveland Clinic advises keeping the head raised after a bone graft.

Skip straws: Cleveland Clinic advises avoiding them for one week after osseous surgery. Cleveland Clinic also advises avoiding hard, crunchy and spicy foods after a gum graft until the surgeon clears them. Gum surgery recovery.

What happens in the first 48 hours after gum surgery?

The first 48 hours after gum surgery are when bleeding settles and swelling builds. Cleveland Clinic expects bleeding after a gum graft to subside within 24 to 48 hours. Swelling continues for three to four days.

Rest: no exercise or heavy lifting for at least 48 hours after a bone graft.
After a gum graft, Cleveland Clinic advises avoiding strenuous exercise for the first week.
Ice the outer jaw in 20-minute cycles, on and then off.
Do not brush or floss the graft until the surgeon says it is safe.
No spitting, vigorous rinsing, smoking or vaping after a bone graft.
No alcohol for at least 2 weeks after a bone graft.
Small graft particles like grains of sand can come out early, which is normal.
After sedation, the ASA notes patients may be told not to drive or drink alcohol for a day.

Cleveland Clinic lists severe bleeding among bone graft risks, and pus or pain that worsens after the first week among signs of graft failure. Call the office for any of these. Implant recovery.

Questions

Who decides on antibiotics after a joint replacement?

The orthopedic surgeon. For patients with past complications from joint replacement surgery, the ADA's chairside guide says antibiotics should be considered only after consultation with the patient and the orthopedic surgeon. When antibiotics are needed, the orthopedic surgeon should recommend the regimen and, when reasonable, write the prescription.

Can I have gum surgery while taking Prolia or Fosamax?

The ADA publishes management strategies for dental care in patients taking these drugs. The ADA calls MRONJ a rare but serious effect of bone drugs such as bisphosphonates and denosumab. An ADA expert panel put the highest reliable estimate of MRONJ at about 0.10% for osteoporosis doses. The ADA notes that stopping bisphosphonates may not remove the risk, so decide with the prescribing physician.

What should I tell the periodontist before surgery?

Tell the periodontist about every medication and supplement, blood thinners, bone drugs and GLP-1 drugs included. Mention heart valve problems, past endocarditis, a heart transplant, congenital heart disease and joint replacements. The AAP also lists diabetes and pregnancy among the conditions that affect periodontal care. Mention smoking, which the AAP grading chart counts as a risk factor.

Can I drink coffee before IV sedation?

Black coffee counts as a clear liquid in the American Society of Anesthesiologists fasting table that the ADA reprints. The table allows clear liquids up to 2 hours before sedation. Milk follows a longer limit, since nonhuman milk empties from the stomach like solids. Follow the office's written instructions, which take priority over the general table.

What if I forget to take my antibiotic before surgery?

Tell the office before treatment starts. The guidelines quoted by the ADA allow the dose to be given up to 2 hours after the procedure if it was missed beforehand. A patient who premedicated for a procedure one day and has another the next day repeats the regimen before the second appointment.
