Hi there,

I was issued a same-day crown, which I thought would be fast and convienent, but in the year since I’ve gotten it, it has fallen out a handle of times!

I went to see a different dentist, who changed the setting of my crown, and gave me a zirconia crown. However, even this one has fallen out! He says that a different porcelain crown will stay in better.

Is this dentist right? Should I go to another dentist? Should I give CEREC another try? What should I do?

Hi there Nancy,

When CEREC same-day crowns are done correctly, they will stay put permanently. CEREC crowns are made from a milled block of ceramic, but no matter what material you use to make a crown, it does not affect whether the crown will stay in.

There are two things that affect whether crowns will stay in. One this is the type of bonding used to cement the tooth into your mouth. The stronger the cement, the better the hold. The other factor is the shape of the tooth. The tooth needs a little bit of tapering to look natural, but the more taper done to the tooth, the harder it will be to bond it into your mouth. It is likely that your tooth was not tapered properly, which is why it keeps falling off.

You should go see a dentist in the area that specialized in crowns. It is very uncommon for crowns to fall out as many times as you have experienced.
