Complete Oral Health and Treament

Despite even the best home care plan to take care of your pet’s teeth, complete oral health and treatment screenings (COHATs), commonly known as cleanings, should always be a regular part of routine pet care. Just like in our mouths, animals have plaque which is a sticky film of bacteria that builds up within just a few hours of brushing. Plaque hides really well under the gum line, in between teeth, and within cracks or natural ridges on the surface of the crown. This is why it is recommended not only to brush your pet’s teeth daily, but why flossing would also greatly benefit teeth that are crowded together. We understand that the reality of brushing their teeth every day is hard for some pet parents (especially cats), but the ability to floss your dog or cat’s teeth may not be comfortable for your pet or safe for your fingers, making regular complete oral health and treatment and other veterinary dental services necessary for your pet’s optimal oral and overall health.

The Problem with Plaque

Plaque eventually traps and combines with saliva, food, and other bacteria in the mouth which over a short period of time hardens into tartar, also known as calculus. As tartar is forming, it’s chemical composition creates a strong bond to the surface of the tooth that makes it very difficult to remove with brushing alone and a COHAT is needed to successfully remove it completely, especially under the gum line and in between crowded teeth.

If the tartar is not removed entirely, it will continually build up leading to gingivitis which is inflammation of the gums that causes redness, swelling and bleeding in your pet’s mouth. This is the mildest form of gum disease and the good news is this level can be reversed with regular brushing at home and regular COHATs under anesthesia.

Developing Periodontal Disease

Once gingivitis develops and if left untreated, it will eventually lead to periodontal disease which is a serious disease resulting in major damage to the soft tissue and bone that supports the teeth. In periodontitis, the inflamed gums begin to pull away from the teeth and form spaces called periodontal pockets that trap even more plaque, tartar, food particles, and bacteria. The body’s immune system fights the bacteria as the plaque spreads and grows below the gum line. Toxins are released from bacteria and the body’s natural response to infection begin to break down the bone and connective tissue that hold teeth in place. If not treated promptly, the bones, gums, and tissue that support the teeth are destroyed beyond repair. In the worst cases, your pet’s teeth will begin to fall out on their own which is a slow, very painful process, or will progress to the point that all severely diseased teeth will need to be surgically extracted.

Impact on Overall Health

Not only do animals with untreated periodontal disease suffer from chronic oral pain and infection, they are also at a higher risk of developing heart, kidney and lung problems. This is especially true as pets age, since periodontal disease is a progressive process that happens over time. A visit to our dog dentist can make a world of difference to your pet’s health, and for those concerned the cost of dog COHATs is not prohibitive. The longer the interval between brushing and COHATs, usually makes it more likely that we are going to find problems during your pet’s oral exam. Regular dog COHAT is incredibly important, cat and dog tooth care is very important responsibility of pet ownership.dental_cleaning

Benefits and Risks

Middle aged and senior pets also require complete oral health and treament screenings under anesthesia on a regular basis. Obviously we will always discuss the risks versus the benefits of anesthesia in any patient, but it is a huge misconception that older pets cannot tolerate anesthesia. That is simply just not true. Here at Harmony Animal Hospital we have a special interest in senior pet dentistry (ages from 10 to 20 years old) and have seen the exceptional benefits to their quality of life and longevity through dental care. Remember that age is not a disease, but dental inflammation, infection, and pain are!

Routine Oral Exams

Depending on how cooperative your pet is, your vet should be able to do a basic oral exam during a routine visit. This is done by lifting your pet’s lip and possibly gently opening the mouth in an attempt to examine all the teeth. This type of oral exam may be enough to show that your pet has gingivitis, plaque, and tartar and can help determine if your pet requires a COHAT. Other common oral problems, such as a broken tooth, loose teeth, oral tumors, and resorptive lesions can also be discovered this way. However, if your pet is uncooperative, painful, or aggressive, even this type of exam may not be possible to perform without sedation or anesthesia.

Full oral exams require the patient to be completely still due to use of sharp instruments, probes, and positioning of their jaw in a very wide open position to assess the teeth in the back of their mouth and the inside surfaces of each tooth. Without anesthesia, many abnormalities could easily be missed and your pet could suffer from chronic pain and infection, as well as, develop progressive periodontitis which leads to tooth loss.

Exams Under Anesthesia

Oral exams under anesthesia also allow for detection of oral tumors, gives us the ability to perform dental radiographs to assess the teeth under the gum line, and makes it possible to treat problems if abnormalities are found during the exam. We make every attempt to perform all necessary therapies during the procedure to minimize your pet’s discomfort, reduce costs to you, and to avoid having to bring your pet back for a separate anesthetic procedure.

Another benefit of administering anesthesia for COHATs is that passing an endotracheal tube as a way to administer oxygen and inhaled anesthesia, also protects the patients airway. There is a lot of water involved with cleaning, plus bacteria is being released with the tartar as it’s being removed, making it possible that water, bacteria and chunks of tartar can be aspirated into the lungs if the airway isn’t protected. This can lead to pneumonia and serious respiratory infections.

Complete Oral Health and Treatment (COHAT)

Steps to a professional cleaning under anesthesia:

  • A COHAT is performed using an ultrasonic scaler and hand instruments to remove all of the plaque and accumulated tartar above and below the gumline, out of the grooves within the crown of the tooth, and from all areas in between teeth. We use disclosing solution afterward to ensure that all of the plaque and tartar has been properly removed.
  • During the cleaning process, small shallow scratches are etched into the enamel of the tooth from the scaler and instruments. These scratches will attract plaque and make it easier for tartar to accumulate, therefore it is necessary to polish every tooth after the cleaning to smooth the surface of the crown. Polishing is performed on every patient using a slow speed hand piece and prophy paste to make the tooth enamel smooth and shiny again.
  • Next a complete oral exam thoroughly evaluates each and every tooth one at a time. This also involves examining the gums, lips, tongue, palate, and throat. A complete oral exam includes probing for and measuring of periodontal pockets, looking for abnormalities including oral masses, loose teeth, abscessed teeth, gingivitis, missing teeth, and much more. Any abnormalities are always charted for future reference as well.
  • Radiographs (x-rays), when indicated, are also performed using a digital dental radiograph machine. Full mouth x-rays should ideally be taken during every dental procedure since 60% of the tooth is below the gum where we cannot see disease, however x-rays should always be taken when there are any abnormalities found on the oral exam including finding of fractured teeth, loose teeth, missing teeth, extra teeth, mis-shaped teeth, malpositioned (crooked) teeth, resorptive lesions, cavities, deep periodontal pockets, oral masses, swellings, and much more.
  • A temporary barrier sealant using Oravet is applied to all the teeth and will lasts for up to two weeks after the cleaning. This is applied to the teeth at the base of the gumline to help prevent plaque buildup. Ideally this should be continued by you at home once a week and we will show you how to do this during your pet’s courtesy two week post-dental recheck exam.

Risks of Anesthesia

It is important to understand that the risk of anesthesia is real, however the reality is that serious complications are VERY RARE and we always take all possible precautions with anesthesia to ensure the safety of your pet:

  • Pre-anesthetic blood work is required prior the day of the dental to make sure your pet doesn’t have any obvious underlying metabolic problems that could delay or prohibit anesthesia for your pet.
  • A pre-medication injection allows our patient to relax, provides pre-emptive pain relief, and allows us to use lower levels of anesthesia.

Every one of our patients will have an IV catheter placed prior to anesthesia for direct venous access during the procedure so that we can more easily and safely administer medications, as well as, IV fluids during the procedure.

We always use the safest, most current anesthetic drugs to minimize reactions, side effects, and complications. Once your pet is induced, an endotracheal tube is gently placed into the airway, all of our patients are maintained on a combination of oxygen and gas anesthesia. Inhaled gas anesthesia allows for easy adjustments to the depth of anesthesia and has the benefit of allowing the patient to breathe pure oxygen and wake up fairly quickly as soon as the gas is turned off.

All patients are thoroughly monitored by a technician and a veterinarian during the entire procedure from start to finish. Our state-of-the-art equipment includes a continuous ECG, heart rate monitor, pulse oxygen saturation (SpO2), blood pressure, capnometer (counts breaths and measures carbon dioxide output), and a digital thermometer. All anesthetized patients’ circulation and body functions are supported with the use IV fluids and their body temperature is regulated with the use of an Equator warming blanket.

It is our policy and commitment to your pet that a dedicated veterinarian and technician team stay with each patient from induction of anesthesia, through any procedures, and until they are sitting-up, awake, and safe.

In the majority of cases, your pet should be able to go home the same afternoon as the procedure. In rare cases when extensive veterinary dental services such as multiple tooth extractions or large oral tumor removals are performed, we may recommend that your pet stay with us overnight so that we can ensure their pain is adequately controlled, to be able to monitor for swelling or bleeding, and that they are fully recovered from anesthesia and able to go home safely.
