Root canal cost in Lake St Louis: frequently asked questions

How much does a root canal cost in Lake St Louis?

A root canal in Lake St Louis, MO typically costs $700–$1,400 USD, about $1,000 on average, as of October 2026. By type: front tooth (anterior) $700–$1,050; premolar (bicuspid) $800–$1,200; molar $1,000–$1,400. These are estimates, not quotes.

Does insurance cover root canals?

Yes, most dental insurance plans cover 50-80% of root canal costs after your deductible. Root canals are typically covered as a basic or major procedure depending on your plan.

Does a root canal hurt?

Most patients say a root canal feels similar to getting a filling, because the tooth is numbed with local anesthetic. The infection beforehand is often more painful than the procedure. Mild soreness for a few days afterward is common and usually eases with over-the-counter pain relief.

Do I need a crown after a root canal?

In most cases, yes. A crown protects the treated tooth from fracturing. Front teeth may sometimes be restored with a filling alone, but molars and premolars almost always need crowns.

How long does a root canal take?

A root canal typically takes 60-90 minutes for most teeth. Complex molars may require 2 appointments. The crown placement is done in a separate visit 2-3 weeks later.
