Whether you need Deep cleaning or not can only be decided by seeing the xrays and clinical examination but $60 for a single tooth is quite expensive. SCRP usually costs around $500 for full mouth and is quite effective and is allowed in insurance. If the condition is not very acute then you can go for Perio Maintenance and this will cost even less and is around $150 for full mouth. So you can take a second opinion from another dentist and try new dentist.
