Every listing on this page has a tick box, and one request goes to all the ones you tick, so you write your name and what is wrong once instead of ringing five receptions in working hours. Practices that have claimed a listing read those requests by email; the rest are told a patient is asking for them, and you can ring them from their own page. If you are in real pain, phone rather than write.

This site does not publish prices, because a price a practice has not agreed to is not a price. What treatments actually involve, what they usually cost across the country and what to ask before you sit down is written up in the patient guides at https://dent-ox.com/patient-guides. Ask the practice for the cost of the first visit when you ring: that one is a straight answer everywhere.

It is every dental practice with a Johnston, IA address on the federal register as it stood on 3 October 2026, minus any that asked to be taken down. Nobody pays to be listed and nobody can pay for a position: the order is who is most likely to answer you, and then distance. Practices claim their own listing for free, which lets them correct it and receive requests by email.
