Overview of the Dental ProcedureEdit
Many pets, especially older pets, have gingivitis (inflamation of the gums) or periodontis (recession of supporting bone and gingival attachment) and have to undergo a dental procedure to clean plaque and calculus from their teeth and to extract diseased teeth. Although dental procedures are increasingly common on nondiabetic animals, the procedure is especially important to minimize underlying low grade infections in diabetic animals. That infection may be hindering regulation. Some caregivers report lower blood glucose readings after an animal finishes its post-procedure antibiotics.
Because of the extra risks, some veterinarians prefer not to perform a dental procedure on a diabetic animal with high or erratic blood glucose levels unless it is considered an urgent situation. This can create a Catch-22 situation because your pet may have very high or erratic blood glucose levels because of dental infection. If you feel this is the case with your animal, you should discuss this with your veterinarian. You also may want to consider consulting a veterinary dental specialist .
A dental procedure requires general anesthesia. General anesthesia poses a risk for any animal (or human), and is a special concern for older or “special needs” animals. Therefore, the caregiver should have a basic understanding of appropriate dental procedures to be able to ask about them beforehand.
A dental normally is an outpatient procedure and, barring complications, your pet should come home the same day. The cost of the procedure can vary widely depending on the clinic and the number of extractions, but you can expect to pay between $250 and $1000 in the US for a dental without overnight hospitalization.
The veterinarian will send you and your pet home with aftercare instructions concerning feeding, antibiotics, and pain medication. The veterinarian may also recommend ongoing dental care, such as brushing, anti-plaque gels, dental chews, and annual dental procedures. You can expect your pet to be somewhat alert once you get him or her home, but perhaps less than 100% for a couple of days.
Pre-procedure testing. If your vet has in-clinic lab equipment, your animal may receive a basic blood panel the morning of the dental. (If your vet does not have that equipment or prefers to send blood out to a lab, that will have to be done before the day of the procedure.) That blood panel will give your veterinarian an indication of whether there are physical conditions other than diabetes that need to be considered in performing the procedure. Among other information, the blood panel will provide a blood glucose reading, and blood urea nitrogen (BUN) and creatinine values to assess kidney health. A T4 test (a thyroid test) also should be run in all cats over 9 years of age prior to going under general anesthesia. Animals with chronic conditions other than diabetes may require more-extensive blood and other testing (such as an echocardiogram or EKG) before undergoing general anesthesia.
Fluids. Some veterinarians may want the caregiver to withhold water from the pet overnight before the procedure. This is generally difficult on and may dehydrate a diabetic animal and you should question such a requirement. Generally, withholding water for more than 2 to 4 hours before the procedure is not necessary.
Food. It is common for your veterinarian to ask you to withhold food for approximately 12 hours before the procedure. This is done to make sure the animal does not aspirate food during the procedure.
Insulin. A cat will receive a normal insulin dose the night before the procedure. The morning of the procedure, it is common to give a cat 1/2 its normal dose. Depending on the individual situation, the veterinarian may or may not give the cat more insulin before it comes home. Consult with the veterinarian whether you should bring the pet’s insulin and syringes into the clinic with you. If you do bring the insulin with the pet, make sure the office completely understands the proper handling of the insulin, and that the pet’s blood glucose should be tested before it receives a shot. Many caregivers prefer not to have the veterinarian’s office give insulin and to wait until the animal is home and eating full meals before again giving insulin.
Antibiotics. A dental procedure releases a large amount of bacteria into the animal’s body. Many suggest that because of diabetics may be more susceptible to infection, the animal should receive pre-procedure antibiotic (anywhere from the day before to seven days before the procedure), as well as a seven-day post-procedure course of antibiotics. A common full-spectrum antibiotic given for this purpose is Clavamox; see the further discussion about this antibiotic here. Note that antibiotics are increasingly not used pre- or even post-procedure in healthy animals; not only do most animals undergoing a dental not have an underlying infection, but one purpose of a dental is to clear out infection, making post-dental antibiotics unnecessary.
During the procedureEdit
General anesthesia. The current standard in veterinary medicine is to use isoflurane or sevoflurane gas. The use of the gas makes it easier to wake the animal if there is an emergency situation during the procedure and makes for an easier post-procedure recovery. As part of administering the gas, the veterinarian will place an endotrachial tube into your pet’s airway. Note that using an ET tube is a must for a dental--besides a means of administering the anesthesia, it also maintains your pet's airway, making sure it stays clear during the procedure.
Make sure to ask who will be monitoring anesthesia. A separate person (not the person doing the procedure) should be monitoring your pet's anesthesia. Also ask about recovery; there should be a technician or assistant assigned to stay with your animal until he or she is awake enough to have the ET tube removed and until your pet's body temperature has normalized.
Fluids. Your pet should have an IV catheter placed (an IV catheter should always be placed when general anesthesia is given) and receive intravenous (IV) fluids during the procedure to help maintain blood pressure. Low blood pressure can cause organ and brain damage. Animals with underlying kidney disease may benefit from receiving fluids before and after the procedure; this is something to discuss with your vet. .
Monitoring vital signs. The veterinarian should have appropriate procedures for monitoring the pet’s breathing, blood pressure, pulse oximetry, heart, and temperature during the procedure.
Pain medication. Optimally, the veterinarian will administer a nerve block during a dental that involves an extraction. If not, and if many extractions are expected, alternate pain management (such as the use of IV opioid drugs) should begin at the same time or slightly before the extractions. Getting ahead of the pain means that your pet may need less pain medication later on, and will be generally more comfortable. Waiting until an animal is awake and painful is unnecessary and should not be common practice.
Animals who have extractions will require pain medication for at least a few days post-procedure. (This is not debatable, despite the fact that the cat or dog may behave normally, because the fact that pain is associated with tooth extraction is well established.) That medication may be in pill form (such as tramadol), or a liquid that can be injected or given by mouth (such as buprenorphine/Buprenex, or Metacam). A liquid form may be better tolerated by an animal that has had several extractions. Common medications include NSAIDs for dogs (drugs such as Metacam, Rimadyl, etc.), opioids (such as buprenorphine) for cats and dogs, or a synthetic opioid (tramadol) for either species. The use of NSAIDs in cats is controversial, and you should discuss the pros and cons with your veterinarian beforehand if that is his or her recommendation.
Butorphanol (brand name Torbuterol) is no longer considered an acceptable pain medication. It is very mild and extremely short-acting.
Ongoing dental careEdit
Before and between dental procedures, swelling and infection can sometimes be reduced, and decay retarded, by brushing pets' teeth with recommended gels.
Sometimes recommended are:
- Zinc ascorbate gel (e.g. Maxi/Guard)
- This is a chemical plaque retardant that slows down tooth decay and gum disease between dental procedures. It's sometimes advertised as "natural".
- Chlorhexidine (gel, or if unavailable, liquid)
- This disinfectant sometimes comes from your vet flavored for easier acceptance by cats and dogs. It retards gum disease and reduces pain. Not a long-term substitute for a dental procedure but may delay the need for the next one. Chlorhexidine for pets is harder to find now than in the past.

Questions to Ask Veterinarians about Dental ProceduresEdit
You should consider asking your veterinarian these questions when planning a dental procedure.
- Will my pet receive a pre-dental blood workup? Will it be an in-house blood panel, or will blood need to be sent out in advance to a lab? Is any other pre-procedure testing needed?
- Barring complications, will I be able to bring my pet home the same day?
- How many tooth extractions do you expect?
- Will you take x-rays before starting, and aftewards as well if there were extractions?
- Who will do the dental? Who will do the extractions?
- Do you have someone else monitoring anesthesia, or is the person doing the procedure supposed to try to monitor anesthesia at the same time?
- Will my pet receive pre-procedure antibiotics and if so when?
- Willl my animal need to be on antibiotics afterwards? For how long?
- What kind of antibiotics do you use? What are the common side effects of this antibiotic? Should I also give my pet a probiotic and if so, which one and how much?
