C3 is a cavity that has reached the pulp of the tooth. The nerve of the tooth has been affected and this causes severe pain. The pain can be induced by hot as well as cold and sweet foods. A spontaneous pain called “zing zing” may occur even at rest. The treatment is completed by removing the nerve of the tooth, performing a root canal, and fabricating and fitting a covering.

In addition, it’s recommended to use a lubricant while drilling deeper holes to help remove debris and dissipate the heat. Furthermore, since plastics expand and contract with temperature changes, make sure you drill a slightly larger hole than necessary to allow room for screw movement without placing stress on the material.

C4 is the terminal stage of tooth decay. The crown, which is the head of the tooth, collapses and only the root of the tooth remains. Because the nerve is dead, you won’t feel any pain. In most cases, when it has progressed to this point, tooth extraction is indicated. Once the tooth has been extracted, the missing tooth is replaced with a prosthetic, such as a bridge, denture or implant.

Once adults lose our teeth, they never return to their original state. Not only they are dissolved by acid produced by bacteria in the mouth, but tooth structure removed by cavity treatment will not regenerate. For this reason, early detection and treatment of tooth decay is of utmost importance.

C0 is an early stage of tooth decay and does not involve holes in the tooth surface. The only characteristic of this stage is the development of “white stains” described as white spots or cloudiness. There is no need to drill the teeth, and fluoride is applied to promote remineralization. You will be advised how to brush so as to improve your hygiene.

The sooner you find cavities, the less we would cut the tooth structure. In particular, we focus on conservative treatment with as little cutting as possible. We strive to preserve as much of the patient’s own teeth as possible and minimize damage.

While drilling through plastic can be done using any power drill, it’s important to have the correct drill bits so you don’t chip or crack the material. Irregular holes and rough edges could lead to cracking, even months after the drilling occurs. Drill bits for plastic are available in a variety of sizes; however, it’s best to consult with a professional before undertaking a project on your own.

C1 is a cavity in the enamel. It is a relatively shallow hole on the tooth surface. It does not cause pain at this stage, but in some cases, cold objects may sting. The treatment is completed by drilling away the bacterial-infested tooth structure and filling it with a composite resin.

C2 is a dentin cavity. The holes in the tooth surface tend to be relatively deep and large. Cold and sweet foods can induce a “toothache”. After the lesion is shaved, treatment is completed with the fabrication and application of a filling or cover.

The most effective drill bits for plastics are spur-point bits, also known as dowel bits. They are specifically angled to make smooth cuts in the material. A spur-point bit has a central point and spurs that keep the bit aligned, maintaining a clean, neat hole. Some soft materials, including plastics, benefit from countersinking before actually drilling. A power drill is used to countersink or create a depression in the material first. Using a countersink bit along with a plastic drill bit ensures that the drill bit remains in the center of the depression. Never use twist bits when drilling plastics; they can splinter and ruin the material.

When drilling plastic, the larger the hole, the slower drill speed you should use since high speeds can melt the plastic. Also, always reduce the drill speed as the drill bit exits the material. Before drilling, it’s best to clamp down the plastic securely to a solid surface and back up the piece you are drilling with a spare piece of plywood underneath. This way the drill bit enters the plywood when it exits the plastic and avoids chipping the surface on the bottom.
