Dental disease affects most dogs over three and most cats over two, and it is the most common reason owners feel their insurance has failed them. The distinction that decides the claim is not the severity of the disease but the purpose of the procedure: prophylaxis is excluded, treatment of pathology is sometimes not.
The routine side of the invoice
A scale and polish under general anaesthesia costs $300 to $700 depending on the practice and the size of the animal, including pre-anaesthetic bloodwork in most quotes. Full-mouth dental radiographs add $100 to $250 and are increasingly standard.
This is classified as preventive care and is excluded by every accident-and-illness policy. Some wellness add-ons contribute a fixed annual amount, typically $100 to $250, which rarely covers the full cost.
The treatment side
Extraction of a diseased tooth requires surgical elevation and closure and costs $30 to $120 per tooth, more for carnassial teeth or canines. A full-mouth extraction in a cat with stomatitis can reach $1,200 to $2,500.
Periodontal disease treatment — scaling below the gumline with closed or open root planing — sits in a grey zone. Some policies cover it when it is treating established disease; others classify the whole dental episode as routine.
| Procedure | Typical cost | Coverage |
|---|---|---|
| Scale and polish | $300–$700 | Excluded (preventive) |
| Dental radiographs | $100–$250 | Often with the dental claim |
| Single extraction | $30–$120 | If dental illness covered |
| Full-mouth extraction (cat) | $1,200–$2,500 | If dental illness covered |
| Wellness dental benefit | $100–$250/year | Add-on only |
The clauses that decide it
Four phrases matter: “dental illness”, “routine dental care”, “periodontal disease” and “pre-existing dental condition”. A policy that covers dental illness but excludes periodontal disease covers very little, since periodontal disease is the majority of dental work.
Some insurers require an annual dental examination documented in the record, or a dental procedure within a defined period before cover, to establish a baseline. Without that, a claim for extractions can be refused as a pre-existing condition.
The economics of waiting
Dental disease is progressive, and the cost curve is steep. A $400 cleaning every 18 months prevents the $2,000 full-mouth extraction case. Insurance does not usually pay for the prevention, which means the owner who insures and skips prophylaxis ends up funding the expensive end of the disease themselves.
- Prophylaxis is excluded by design on every standard policy.
- Extractions may be covered when the policy includes dental illness.
- Periodontal disease exclusions remove most of the category.
- A documented dental baseline protects later claims.
A single line reading “dental — $1,400” is likely to be treated as routine. An itemised invoice separating radiographs, anaesthesia and eight extractions supports a treatment claim.
Key takeaways
- Purpose, not severity, determines dental cover.
- Periodontal exclusions are the clause to look for.
- A documented baseline prevents pre-existing refusals.
- Prevention is cheaper than treatment even when uninsured.
