Restorative dentistry is the work of repairing what is already damaged — rebuilding a tooth that has broken, decayed, or been worn down until it no longer does its job. The goal is function first: chewing comfortably on both sides, without pain, without avoiding foods.
The right restoration depends mostly on how much healthy tooth structure remains. That single question separates a filling from a crown, and a crown from an extraction, more reliably than any other factor.
Fillings, crowns, and where the line falls
A composite filling replaces a modest amount of lost structure and is bonded directly into the tooth in one visit. It relies on the surrounding tooth for strength, which is why it works well for small and moderate cavities and poorly for large ones.
A crown covers the entire tooth. When decay or a fracture has taken enough structure that the remaining walls would flex or split under chewing force, a filling becomes a temporary measure and a crown becomes the durable one. Teeth that have had root canal treatment usually fall on the crown side of that line, because they are more brittle than living teeth.
Same-day crowns with CEREC
Traditionally a crown meant two visits with a temporary in between: prepare the tooth, take an impression, send it to a laboratory, and fit the finished crown weeks later. CEREC technology allows the crown to be designed and milled in the office, so the tooth is prepared and the permanent crown fitted in a single appointment.
The practical benefit is not just speed. There is no temporary crown to come loose, no second round of anesthetic, and no interval during which the prepared tooth is vulnerable. Not every case suits same-day fabrication, and we will say so when it does not.
Root canal treatment, minus the mythology
Root canal treatment has a reputation that modern practice does not support. The procedure removes infected tissue from inside the tooth, disinfects the canal system, and seals it. With effective anesthetic, the treatment itself is comparable to having a filling placed — the pain people associate with root canals is almost always the infection that made the treatment necessary, not the treatment.
The alternative to a root canal on an infected tooth is losing the tooth. Keeping your own root in place preserves the bone around it and the way your bite is distributed, which is why saving a tooth is generally preferable to replacing it whenever the tooth can be reliably restored afterward.
Replacing missing teeth with bridges and dentures
A bridge fills a gap by anchoring a replacement tooth to the prepared teeth on either side. It is fixed in place and does not come out, at the cost of involving two neighboring teeth that may be perfectly healthy.
Dentures replace teeth removably, either a full arch or a partial that clasps to remaining teeth. Modern partials can replace a single missing tooth or a run of back teeth without involving the neighbors at all. Both bridges and dentures restore chewing and appearance; which suits you depends on how many teeth are missing, where they are, and the condition of what remains.
Living with dentures
New dentures take adjustment. Speech and chewing feel unfamiliar for a while, sore spots are common in the first weeks, and adjustment appointments are a normal part of the process rather than a sign something went wrong.
Over the longer term, the ridge of bone underneath a denture gradually changes shape, so a denture that fit well initially will eventually loosen. Relining refits the base to the current shape of the ridge. A denture that has started to slip, click, or rub is usually telling you it needs relining, not replacing.
