Crowns require precision.
Crowns are expensive and we respect your decision to invest in your dental health, so we will do our best to help your investment last.
A crown is an intricate procedure, every area prepped (natural tooth removed) needs to be protected by the new crown.
How the crown fits the natural tooth is imperative to the longevity of the tooth and crown.
A diagnostic perpendicular X-ray ("Bitewing") can show the fit of the crown in between the teeth, and, by or under the gumline.
We never attach a crown (cement/glue) without our patient’s consent on the:
SHADE, SHAPE, FIT, & BITE POSITION.
- All porcelain crowns (ex: zirconia) are stronger than porcelain fused on top of metal crowns (PFM).
- Any irregularities (gaps/open margins and ledges/excess) around where the crown meets the natural tooth can trap bacteria and acids; which will increase the likelihood of decay and chances of early failure of the crown &/or tooth.
- Having the tooth prepped with precision and accommodating the position can prevent excessive adjustments at delivery of the crown.
- Making excessive adjustments on a crown can make the crown thinner which can cause fractures or holes and early failures.
- Adjusting the opposing tooth can cause irritation and/or weaken the natural tooth or restoration.
- Not addressing symptoms of a failing nerve in a tooth prior to delivery of a crown can result in damaging the new crown.
- Drilling through a crown after delivery to do a root canal will break the seal and integrity of the crown.
