I’m sure you have noticed that dry doesn’t really keep teeth clean, so if that’s the only reason for feeding it then take a pass. Balanced raw is best. It has fresh specie appropriate food sources. After that, freeze dried, then dehydrated, because they are less processed and are usually a good source of meat proteins. Next would be canned, it is heat damaged but it has appropriate moisture and it is less processed than kibble and less starch than kibble. Last is kibble which is high in carbs and very processed.
For dental health, try brushing and raw meaty bones.
