I just had my implant #19 a month ago and I have to wait 4 months to have a crown to put on top of the implant. My dentist told me I have a choice of either procelain or gold. From what i learnt on line, gold crown is better for molar and procelain is better for front teeth. Since mine is a molar, so is gold crown better? Anyone could comment on the difference? Thank you.
