Dental fillings are an important part of maintaining good oral health. Getting a filling can help prevent further decay and protect damaged teeth. Modern dental fillings come in a variety of materials like metal, porcelain, resin, and glass ionomer. Choosing the right filling type depends on the location of the cavity, extent of damage, cost, insurance coverage and your personal preferences. This comprehensive guide will provide an overview of the most common types of dental fillings, the procedures involved, costs, benefits and risks.
Types of Dental Fillings
Amalgam Fillings
Amalgam fillings have been used for over 150 years and are made from a mixture of metals including silver, copper, tin and mercury. This material is malleable, durable and can withstand the high pressures of chewing. Amalgam fillings are strong, inexpensive, and long lasting. They are especially good for large cavities where they can bear heavy biting forces. The main downside is that they are not tooth colored and stand out with their silver hue against natural teeth.
Composite Resin Fillings
Composite resin is a tooth colored filling made from plastic and fine glass particles. These fillings are also known as white, plastic or bonded fillings. Composite fillings match the shade of natural teeth and blend in seamlessly. They allow for maximum preservation of tooth structure since they chemically bond to the surface. Composite resins can be used for both front and back teeth. However, they wear faster than amalgam and may need replacement sooner. They are more expensive than amalgam but their natural appearance makes them a popular choice.
Porcelain Fillings
Porcelain fillings, also called inlays or onlays, are made by a dental technician in a laboratory using ceramic material. They are tooth colored and create a natural looking smile. Porcelain is resistant to staining and can be matched perfectly to the surrounding tooth shade. These fillings are ideal for larger cavities in the back teeth where they can provide strength against heavy chewing forces. The tooth does require some removal to allow for the fit of the porcelain filling. This is a more expensive option but provides good durability and aesthetics.
Glass Ionomer Cement Fillings
Glass ionomer cement fillings are made from a mixture of acrylic acids and fine glass particles. They are tooth colored but do not have the translucency of composite resin fillings. These fillings release fluoride which provides an extra layer of protection against decay. They bond well to tooth structure and cost less than composite resin. Glass ionomers are most suitable for small non-biting surface cavities. They are not recommended for large fillings or back teeth since they lack the strength of other materials.
Temporary Fillings
Temporary fillings may be placed while waiting on a permanent restoration. They act as a protective bandage, keeping out food and bacteria. Some common types of temporary fillings are zinc oxide-eugenol and Cavit. Temporary fillings fall out easily and should be replaced as soon as possible.
Filling Procedures
The dentist will begin by examining the tooth and taking x-rays to determine the extent of decay. Numbing medication is applied and the decayed material is completely removed. The cavity is cleaned and shaped to allow for a proper fitting filling. Your tooth may be given a conditioning liquid to help the filling adhere. The filling material is then placed, shaped and hardened with a curing light. A drilling tool smooths out the surface for a natural feel. Finally, a polishing paste is used to buff the new filling. You should avoid chewing or putting pressure on the filling for at least an hour.
Cost of Fillings
The cost of dental fillings depends on the material, size of the cavity, insurance coverage and the dentist’s fees. Amalgam fillings are the most economical, starting at around $50-150 per tooth. Composite fillings range from $90-250 per tooth. Porcelain fillings are the highest, from $250-2500 since they involve lab work. Insurance can cover 50-80% of costs. Additional factors like tooth-colored materials versus amalgam also affect costs. Talk to your dentist about the options for your situation.
Benefits of Dental Fillings
- Stop decay and prevent further damage
- Restore form and function
- Prevent infection entering the tooth
- Relief from pain and sensitivity
- Avoid root canal therapy or extraction
- Maintain a properly aligned bite
- Preserve remaining tooth structure
- Improve smile appearance with tooth colored fillings
Risks of Dental Fillings
- Tooth sensitivity to hot and cold right after the procedure
- Possible irritation or damage to nerve tissue from drilling
- Temporary pain, swelling and inflammation as anesthetic wears off
- Risk of cracking the tooth with larger fillings
- Material shrinkage leading to secondary decay
- Damage to other teeth while numbed during the procedure
- Allergic reactions in rare cases to composite resin
- Mercury toxicity risks from amalgam fillings
Proper Care of Fillings
It’s important to take good care of your fillings to increase their longevity:
- Maintain excellent oral hygiene by brushing twice and flossing once daily
- Use fluoride toothpaste and mouthwash to strengthen enamel
- Avoid chewing hard foods like nuts, ice or hard candy
- See your dentist regularly for examinations and cleanings
- Report any cracks, pain or deterioration right away
- Modify habits like teeth grinding that put excess force on fillings
- Get new fillings as soon as existing ones need replacement
Conclusion
Modern dentistry offers several options for restoring damaged teeth suffering from decay. Amalgam and tooth colored composite resin are commonly used for fillings in both front and back teeth. Porcelain inlays or onlays provide durable and aesthetic restorations for larger cavities. The choice depends on the size and location of decay, cost factors and personal preferences. With proper oral care and hygiene, dental fillings can last many years before needing replacement. Regular dental visits are key to monitoring and maintaining your fillings. Keeping your natural teeth healthy should always be the priority.
