Filling cavities with liquid plastic is a new cavity treatment that offers an alternative to traditional fillings. This procedure uses liquid resin infiltration to fill small cavities without drilling or removing any tooth structure. It is a conservative, no-shot, and no-drill treatment that is popular with patients as it is less invasive and more comfortable. While this treatment is currently only available in clinical trials, it has the potential to revolutionize the field of dentistry if adopted nationally. However, it is important to note that filling cavities at home with temporary kits can be risky and may not effectively address the underlying decay. Seeking professional dental treatment is always recommended for safer and more effective results.
Characteristics and their values regarding filling a cavity with liquid plastic
| Characteristics | Values |
|---|---|
| Type of filling | Direct or indirect. Direct fillings are placed in the mouth directly and do not require a dental laboratory or temporary restoration. Indirect fillings are made in a lab before being placed in the mouth. |
| Filling materials | Amalgam (silver in color, contains mercury mixed with silver, tin, zinc, and copper), composite resin (tooth-colored), porcelain (tooth-colored), glass ionomer (tooth-colored, releases fluoride to prevent decay), gold (an alloy of copper and gold), or cement. |
| Procedure | The decayed or damaged portion of the tooth is removed, and the cavity is dried. The filling material is then mixed and pressed into the cavity, with extra material being removed. |
| Cost | The cost of a filling depends on the location in the mouth, the material used, and the size of the cavity. |
| Risks | Using incorrect materials in DIY filling kits can lead to food, liquid, and decay getting into the hole, potentially causing tooth loss or a root canal. |
| Alternatives | A new cavity treatment uses liquid resin infiltration, which is FDA-approved and does not require drilling or filling. However, it only works for small cavities between teeth or on smooth surfaces. |

The risks of using at-home filling kits
Although at-home filling kits are increasingly popular, they come with several risks. Firstly, they do not address the underlying tooth decay, which is the source of the problem. Without removing the decay, the issue will worsen, leading to severe dental problems that may require complicated treatments.
Secondly, at-home fillings can cause discomfort or severe pain while eating or chewing. The pressure of chewing can irritate the sensitive dentin layer, causing pain. Fluids can also seep beneath the filling, triggering sensitivity and pain, especially with temperature changes. Additionally, temporary fillings can alter your bite, leading to further discomfort and an increased risk of damaging the tooth, such as cracking or chipping.
Another risk is that at-home fillings do not replicate the shape of your tooth accurately, which can negatively affect your bite pattern and cause teeth to shift. This can result in excruciating jaw pain, headaches, and toothaches. Over time, shifted teeth can also alter the appearance of your face and jawline and impact the health of your jaw joint.
Furthermore, the filling materials in at-home kits are not as strong or durable as those used by dentists. They are more likely to break or fall out, leading to increased jaw pain and further tooth decay, which may result in serious health issues. The materials may also not match the colour of your teeth, resulting in aesthetic concerns.
Lastly, at-home dental procedures can lead to various long-term problems and exacerbate the issue. It is important to seek professional dental care to ensure proper diagnosis and treatment, as dentists have the skills, expertise, and specialised tools to address oral health issues effectively.

How to prepare a cavity for filling
If you suspect you have a cavity, it is important to see a dentist as soon as possible. Cavities can develop without causing any noticeable symptoms, but some signs to look out for are toothache, tooth discolouration or staining, holes or cracks, and sensitivity to hot and cold temperatures. If left untreated, cavities can grow larger and may reach the pulp of the tooth, requiring a root canal instead of a simple filling.
Before a dentist can place a filling, they must first prepare the cavity by removing any decayed or damaged portions of the tooth. This is done using dental tools such as an excavator, and local anaesthetic may be used to numb the area and reduce any discomfort. Once the decay is removed, the cavity is cleaned to ensure that only healthy tooth structure remains. In some cases, a calcium hydroxide lining material may be placed in the cavity, particularly if the cavity is deep.
For amalgam fillings, the tooth must be prepared in a specific box shape to accommodate the filling material. This may involve the removal of additional tooth material. A metal matrix band may be used to create a temporary wall for the amalgam to be supported on until it sets. The dentist will then use a packer to pack the cavity with the amalgam, layer by layer, to ensure a sturdy and secure restoration.
For composite resin fillings, the dentist may simply bond the material onto the tooth without the need for extensive cavity preparation. The composite filling is placed into the cavity or onto the tooth and shaped by the dentist. A curing light is then used to set the filling, and a bite check is performed to ensure the filling is not too high or large.
It is important to discuss your treatment options with your dentist and decide on the best type of filling for your situation. Other types of fillings include gold, porcelain, and glass ionomer, each with its own unique characteristics and benefits.

The process of filling a cavity with cement
Filling a cavity with cement, or a dental filling, is a common procedure that helps repair tooth cavities and fix minor chips and cracks in your teeth. The process typically involves the following steps:
Removing the decayed portion of the tooth
First, the dentist will remove the decayed, defective, or damaged portion of the tooth. This step is crucial to prevent the cavity from growing larger and causing further issues.
Cleaning the cavity
Once the decayed portion is removed, the dentist will clean the cavity to prepare it for the filling. This may involve shaping the cavity to ensure a proper fit for the filling material.
Choosing the filling material
There are various dental filling materials available, including amalgam, composite resin, porcelain, and glass ionomer. Amalgam fillings are silver-colored and contain mercury mixed with other metals, while composite resin and porcelain fillings are tooth-colored and designed to blend in with the natural tooth. Glass ionomer cement (GIC) is also an option and is often used as a temporary filling material.
Placing the filling
The dentist will then place the filling material into the prepared cavity. For amalgam fillings, this involves mechanical compression, while composite resin fillings are placed in increments and cured with UV or LED light. Porcelain fillings, on the other hand, are prepared in a lab as an inlay or onlay and later bonded to the tooth cavity with dental cement.
Adjusting the bite
After the filling has been placed and allowed to set, the dentist will adjust your bite to ensure the filling does not interfere with your normal chewing or biting patterns. This step helps prevent any discomfort or issues with your bite after the procedure.
Post-procedure care
After the filling procedure, you may experience mild sensitivity or discomfort, which can be managed with over-the-counter painkillers. It is important to maintain good oral hygiene and visit your dentist for regular check-ups to ensure the filling's longevity and maintain your oral health.

The types of filling materials available
There are several types of filling materials available to treat cavities. These include:
Amalgam
Amalgam fillings are made from a mixture of metals, including silver, tin, copper, and mercury. They are silver in colour. Amalgam fillings have been used in dentistry for over 100 years and are known to be durable and long-lasting. However, some people may have concerns about the potential health effects of mercury vapors from these fillings.
Composite Resin
Composite resin fillings are tooth-colored and are made from a mixture of plastic and glass particles. They consist of a resin base with powdered quartz, silica, or glass. Composite fillings are a popular choice as they blend in with the natural tooth colour and can be used for minor chips and cracks.
Glass Ionomer
Glass ionomer fillings are also tooth-colored and are made from silica glass powder or a mixture of glass and acrylic. They release fluoride to help prevent further tooth decay. Glass ionomer fillings are often chosen for their aesthetic value and ability to protect teeth.
Gold
Gold fillings are made from an alloy of gold, copper, and other metals. They are a less common but still effective option for cavity repair. Gold fillings are typically more expensive than other types of fillings.
Porcelain
Porcelain fillings, also known as ceramic fillings, are tooth-colored and made from porcelain or other ceramic materials. They offer a natural-looking option for restoring teeth and are often chosen for their aesthetic value.
The choice of filling material depends on various factors, including the location and size of the cavity, as well as the patient's preferences and budget. It is always recommended to discuss treatment options with a dentist to determine the most suitable filling material for your specific situation.

The cost of filling a cavity
The type of filling material is a significant factor in determining the cost. Metal amalgam fillings, made from a mixture of metals such as silver, tin, or copper, are often the cheapest option, ranging from $50 to $200 for 1-2 teeth or $150 to $400 for 3 or more teeth. Amalgam fillings are durable, but they have a noticeably different color from the teeth and may expand, creating cracks. Composite resin fillings, which match the color of tooth enamel, are more expensive than amalgam but less costly than gold or porcelain. The average cost for a composite resin filling is around $191 per tooth. Gold fillings are noticeable and may cost anywhere from $100 to $1,150 per tooth or more. Porcelain fillings, or inlays, are the most expensive option, ranging from $300 to $4,500 per procedure.
The size of the cavity also impacts the cost, with larger cavities requiring more material and, therefore, increasing the price. Additionally, the location of the tooth affects the cost, with front teeth being less expensive to fill than those in the back, which are more difficult to access. The severity of decay is another factor, as extensive decay requiring complex dental work will be pricier than minor damage.
The number of fillings needed also adds to the overall cost. If multiple teeth require filling, each additional filling will increase the total expense. Finally, the cost of dental work, including fillings, tends to be higher in areas with a high cost of living.
It is worth noting that some insurance providers cover up to 80% of the cost of fillings, and dental plans can help make the procedure more affordable. Without insurance, the average cost of a filling ranges from $160 to $600, with prices as low as $100 or as high as $4,000.
