Removing Tartar from a dog's teeth costs from as low as $100.00 to as much as $300.00 and that is without sedation.
If the dog requires sedation then the cost could go up to $400.00 to $600.00 for the dogs teeth to have the tartar removed.
If the dog does okay without needing anesthesia then it can be done more cheaply but some dogs have behavior problems around other people and need sedation to have their teeth cleaned.
The last time I took a small dog in to have his teeth cleaned and tartar removed it cost me $200.00 and he didn't require sedation.
