Introduction
Dental fillings can be made of a variety of materials, including metals, polymers, glass, or other substances, and are used to restore or repair teeth. They have a variety of uses, with one of the most popular being the restoration of tooth regions that a dentist had to extract owing to decay, or cavities. Additionally, fillings are used to repair teeth that have cracks, breaks, or wear and tear from behaviors like nail-biting or grinding their teeth.
What Are the Materials Used for Filling?
Dental filling materials encompass a variety of options:
1. Porcelain.
2. Gold.
3. Tooth-colored composite resin fillings, made from plastic and glass materials.
4. Silver amalgam (which contains mercury blended with silver, tin, zinc, and copper).
The choice of filling material depends on factors such as the location and extent of the decay, the cost of the filling material, patients’ insurance coverage, and the dentist’s recommendation. These factors are carefully considered to determine the most suitable filling type that will effectively address the specific dental needs.
What Are the Indications of Dental Filling?
Sugars and carbohydrates from food and drink interact with the oral environment and cause decay. Decay-causing microorganisms produce an acidic environment. The enamel on the tooth is attacked by this acid, which causes mineral loss. Minerals from the enamel are continuously lost due to repeated acid contact, especially when sugary and starchy meals and drinks are consumed often. A white area that represents this mineral loss denotes the beginnings of deterioration. The early stages of tooth decay allow for prevention or reversal. By absorbing minerals from saliva and fluoride from toothpaste, enamel can heal itself. This procedure may also benefit from fluoride administration by a dentist or dental hygienist. However, if the mineral loss outpaces the body's ability to heal itself, the enamel becomes brittle and eventually crumbles, creating a hollow.
In cases of more serious decay, a sizable hole may form, possibly resulting in the tooth's total loss. If left unattended, untreated dental decay can result in discomfort, infections, and finally tooth loss.
What Are the Advantages of Various Dental Fillings?
Different dental fillings have different advantages. These are;
1. Gold:
-
Durability: Lasts for at least 10 to 15 years. Gold fillings have an aesthetic appeal for some people.
2. Amalgams (Silver Fillings):
-
Durability: It has a minimum 10 to 15 year lifespan.
-
Cost-Effective: These fillings are less expensive than composite fillings.
3. Composite Fillings (Tooth Colored Filling):
-
Aesthetic: It matches with the current teeth's color fairly well in terms of appearance.
-
Bonding Strength: These restorations strongly adhere to the preexisting tooth, adding more stability.
-
Versatility: Frequently employed in repairs other than cavity filling.
-
Conservative: Compared to amalgams, composite fillings are more conservative and sometimes less tooth removal is necessary.
4. Ceramics or Porcelain:
-
Outstanding Durability: Such fillings may last for more than 15 years.
5. Glass Ionomer (Glass and Acrylic Material):
-
Fluoride Release: Fluoride is released by these filling materials, which aids in the prevention of additional tooth decay.
-
The strength of these restorations is similar to that of amalgam restations.
What Are the Disadvantages of Different Dental Filling?
1. Gold:
-
Cost: Such restorations are expensive compared to other fillers.
-
Multiple Visits: The placement process can call for more than one office visit.
2. Amalgams (Silver Fillings):
-
Teeth reduction: More tooth structure removal might be necessary to make enough room for the filling.
-
Aesthetic Issues: These fillings give the surrounding tooth structure a grey tint due to leaching out of the amalgam.
-
Fractures Risk: Wider expansion and contraction in the presence of saliva and oral environment lead to a higher risk of tooth cracking and fracture.
-
Allergic Potential: Some people may be allergic to the ingredients in amalgam. Also, this may cause mercury toxicity.
3. Composite Fillings in Tooth Color:
-
Durability: Such restorations last no more than five years, which is less time than other materials.
-
Prone to Chipping: According to the environment, there may be chipping fractures or debonding of such restorations.
-
Cost: Compared to amalgam fillings, it might be up to twice as expensive.
-
Time-Consuming: This may take longer to complete and may necessitate several visits.
4. Ceramics or Porcelain:
-
Cost: This can be as costly as gold dental fillings.
5. Glass Ionomer (Glass and Acrylic Material):
-
Weak Material: These filling materials are less resilient than composite resin.
-
Wear and Breakage: Glass ionomer fillings are more susceptible to wear and breakage.
-
Lifespan: These filling materials have a short life span of no more than five years.
-
Comparable Cost: The prices of glass inomer cement are comparable to those of composite fillings.
What Are the Other Types of Dental Filling?
A. Indirect Fillings: Indirect fillings are created in a dental laboratory and go through a two-step process, as opposed to composite or tooth-colored fillings. When there is not enough healthy tooth structure to sustain a filling but the tooth isn't too injured to require a crown, they are an option worth considering. During the first visit, decay or old fillings are taken out, and an impression is made to record the shape of the tooth and its neighboring teeth. The indirect filling is produced to order at a dental lab using this impression. A temporary filling is put in to protect the tooth while the restoration is being made. The temporary filling is taken out at the subsequent appointment, and the dentist checks the indirect restoration's fit. The filler is firmly cemented into place if the fit is satisfactory.
Inlays and onlays are the two types of indirect fillings.
-
Inlays: These are placed within the cusps on the chewing surface of the tooth and resemble typical fillings.
-
Onlays: Onlays are more extensive than inlays and are frequently referred to as partial crowns since they cover one or more cusps.
Inlays and onlays, which can be made of porcelain, gold, or tooth-colored composite resin, are more durable and long-lasting than ordinary fillings, lasting up to 30 years. Even though they weaken the tooth structure, this effect is considerably less than what regular fillings have on the tooth.
Direct inlays and onlays are an alternate strategy that uses the same steps as indirect ones. Direct inlays and onlays are different since they are made and fitted at the same dental office visit. Depending on the amount of good tooth structure that is still present and aesthetic factors, one should choose between inlays and onlays.
B. Temporary Fillings: In dental care, temporary fillings are used for the following reasons:
-
Multiple Appointments: Temporary fillings are required when the filling process necessitates more than one session, such as when placing gold fillings or performing indirect fillings using composite materials.
-
After a Root Canal: If the pulp gets irritated during the procedure, temporary fillings are frequently utilized to allow the tooth's nerve to calm down.
-
Managing Tooth Irritation: Temporary fillings are used to reduce tooth sensitivity and irritation, giving the nerve time to settle down.
-
Emergency Dental Care: Temporary fillings are utilized in emergency dental conditions, such as those involving acute toothaches, to provide comfort right away until a long-term remedy is put in place.
It is crucial to keep in mind that temporary fillings are just that—temporary. They are not intended for continuous use. Within a month, these fillings usually disappear, break, or wear out. To have the temporary filling replaced with a permanent one during the follow-up visit, it is essential that the patient visit the dentist within the stipulated time. Failure to complete this stage could result in dental problems or tooth infections.
What Are the Procedures for Dental Filling?
A local anesthetic will first be applied by the dentist to numb the region around the injured tooth. Whether a drill, air abrasion tool, or laser is used to remove decay, it depends on the dentist's skill, training, and equipment options, as well as the location and severity of the decay.
The dentist will inspect the area while the tooth is being removed to make sure all decay has been removed. The dentist will carefully clean the cavity to get rid of bacteria and debris once the decay has been removed. If the deterioration is present close to the root, the nerve may be protected by the placement of a glass ionomer, composite resin, or other material liner. The dentist will refine and polish the filling material for a flawless finish once it has been applied.
Additional steps are taken in cases of teeth-colored restorations;
1. Layered Application: The tooth-colored material is applied in many levels following the removal of decay and thorough washing.
2. Curing Process: To ensure adequate curing and hardening of the material, each layer is hardened using a specialized light.
3. Trimming and shaping: Following the multilayering, the dentist will shape the composite material to produce the required shape. Trimming off any extra material requires precision.
4. Polishing: To provide a flawless and natural appearance, the final restoration is meticulously polished.
In certain cases, dental fillings are replaced. Three main factors could require replacing dental fillings:
-
Usual Wear and Tear: Fillings may gradually deteriorate, chip, or crack as a result of grinding, clenching, or chewing. Even if the patients can not, dentists can identify these problems during routine checkups.
-
Breakage of Filling and Decay Forms: More decay can develop if food and germs penetrate the filling due to a broken seal between it and the tooth. If left untreated, this may result in severe tooth issues.
-
Significant Filling or Significant Decay: There might not be enough tooth left to support a new filling if the existing filling is large or if there is a lot of rot. In these situations, a dentist may decide to substitute a crown, a more durable tooth covering, for the filling.
Conclusion
Fillings are placed in teeth to restore the functions of decaying or broken ones. They also protect the teeth' structure and underlying pulp. The choice of dental filling depends upon various factors like esthetics, economic condition, and the extent of the lesion.
