Discover how silver diamine fluoride (SDF) can help stop the progression of certain cavities—often without drilling or anesthesia.
If you've been told that you or your child has a cavity, you may immediately think of a filling, a dental drill, and local anesthesia. While traditional restorative treatment remains appropriate for many cavities, there are situations where a more conservative approach may be considered.
Silver diamine fluoride, commonly called SDF, is a professionally applied treatment that can help arrest certain areas of active tooth decay. It may be particularly useful for patients who are very young, have difficulty tolerating traditional dental treatment, or have other circumstances that make restorative treatment challenging.
At Newark Smiles Dental, we take the time to evaluate each situation individually and discuss the available treatment options with you.
What Is Silver Diamine Fluoride?
Silver diamine fluoride is a topical dental treatment containing silver and fluoride. When professionally applied to an active area of tooth decay, SDF can help inhibit the progression of the lesion.
The American Dental Association recognizes SDF as one option for nonrestorative management of certain carious lesions. In the United States, SDF is FDA-cleared for the treatment of tooth sensitivity, while its use to arrest dental caries is considered an off-label use.
Because SDF is applied directly to the affected area, treatment can often be completed without removing tooth structure with a drill
How Does SDF Work?
SDF combines the properties of silver and fluoride.
Silver has antimicrobial properties, while fluoride supports the mineralization and strengthening of tooth structure. Together, these effects can help slow or arrest the progression of certain cavities.
However, SDF does not rebuild tooth structure that has already been lost. If a cavity has created a significant hole or weakened the tooth, additional restorative treatment may still be necessary.
Who May Benefit From SDF?
SDF may be considered in a variety of situations, including:
- Young children: Some children may not yet be comfortable with longer restorative procedures
- Patients with dental anxiety: SDF may provide a more conservative option in appropriate cases.
- Older adults: It may be useful for certain patients who have difficulty tolerating more involved treatment
- Patients with certain access or health considerations: SDF can sometimes provide an interim approach when immediate restorative treatment isn't practical.
- Certain active cavities: Some lesions may be appropriate for nonrestorative management.
Whether SDF is appropriate depends on the individual tooth, the extent and location of the decay, and the patient's overall dental and medical circumstances.
What Happens During an SDF Treatment?
If your dentist determines that SDF may be appropriate, the tooth will first be carefully examined. X-rays or other diagnostic tools may be used when necessary.
The tooth is isolated and dried, and a small amount of SDF is carefully applied directly to the affected area.
The procedure is generally quick and does not require drilling or local anesthesia.
Your dentist will explain what to expect before treatment and answer any questions you may have
An Important Consideration: Tooth Discoloration
One of the most important things to understand about SDF is that treated areas of tooth decay typically turn dark brown or black.
This discoloration is a result of the treatment interacting with the decayed tooth structure. It is an expected effect of SDF and should be discussed before treatment, particularly when the cavity is located on a visible front tooth.
For this reason, your dentist may recommend other treatment options when appearance is a major consideration.
Does SDF Replace a Filling?
Not necessarily.
SDF can help arrest active tooth decay, but it does not restore tooth structure that has already been lost.
For some patients, SDF may be the primary approach for managing a particular lesion. In other situations, it may be used as an interim treatment before a filling, crown, or another restoration.
Your dentist will evaluate the tooth and discuss which approach is appropriate for you.
Is Follow-Up Necessary?
Yes.
SDF treatment requires monitoring by a dental professional. In some cases, additional applications may be recommended because a single application may not provide sustained benefit. Your dentist will determine the appropriate follow-up schedule based on your individual circumstances.
Regular dental examinations remain important after SDF treatment so your dentist can monitor the treated area and your overall oral health.
Is SDF Safe?
SDF has been studied and used internationally for many years. The ADA recognizes it as an option for managing certain carious lesions when used as part of a patient-specific treatment plan.
As with any dental treatment, there are potential considerations and limitations. Your dentist should review your medical and dental history, discuss the benefits and potential side effects, and explain other available treatment options before treatment.
How Much Does SDF Cost?
The cost of SDF treatment varies depending on the number of teeth treated, your individual treatment needs, and your dental insurance benefits. Because SDF application can be relatively quick and does not require the same materials or laboratory work as some restorative procedures, it may be a more conservative treatment option in appropriate cases.
Our team can review the expected cost and your available insurance benefits before treatment.
Key Takeaways
- Silver diamine fluoride stops active decay using silver's antimicrobial action and fluoride's remineralizing effect, all without drilling or anesthesia.
- It's especially useful for young children, anxious patients, older adults, and anyone needing a bridge to more extensive treatment.
- Treated decay turns dark permanently, so it's typically used on back teeth or baby teeth rather than visible front teeth.
- SDF halts decay but does not rebuild lost tooth structure, and follow-up applications or restorations may still be needed.
- It's a fast, low-cost, well-researched option that fits naturally into a routine dental visit.
Frequently Asked Questions
Does SDF hurt?
SDF application generally does not require drilling or local anesthesia. Some patients may notice a metallic taste or temporary irritation if the material contacts surrounding soft tissue.
Will SDF make my tooth black?
The decayed portion of a tooth treated with SDF will typically become dark brown or black. This is an expected effect of the treatment and should be considered when discussing your treatment options.
Can SDF completely remove a cavity?
No. SDF can help arrest the progression of certain areas of tooth decay, but it does not remove the decay or rebuild tooth structure that has already been lost.
Will I still need a filling?
Possibly. Some teeth treated with SDF may later require a restoration, depending on the amount of tooth structure that has been lost and other clinical factors.
Can children receive SDF?
SDF may be used in children when a dentist determines that it is appropriate. The dentist should evaluate the child's individual needs and discuss the treatment, alternatives, and potential discoloration with the parent or guardian.
How often will SDF need to be applied?
The appropriate follow-up schedule varies. Some patients may need additional applications, while others may require restorative treatment. Your dentist will monitor the treated tooth and recommend follow-up based on your individual needs.
Is Silver Diamine Fluoride Right for You?
SDF can be a useful, minimally invasive option for managing certain areas of tooth decay, but it isn't the right treatment for every cavity or every patient.
At Newark Smiles Dental, we take a personalized approach to treatment. We'll examine your teeth, explain your options, and help you understand the benefits and considerations of each approach.
