A Quick, Noninvasive Way to Help Stop Tooth Decay
When a child has a cavity but is not ready for conventional restorative treatment, silver diamine fluoride may help slow or stop the decay from progressing. The liquid is applied directly to the affected area without drilling into the tooth, making it a useful option for some young, anxious or medically complex children.
At Longhorn Pediatric Dentistry and Orthodontics, Dr. Reza Arzegar evaluates each cavity carefully to determine whether silver diamine fluoride is appropriate or whether your child needs a filling, crown or another treatment. Dr. Arzegar is a board-certified pediatric dentist with 20 years of experience and has completed thousands of pediatric restorative cases.
Help protect your child’s tooth before decay becomes more extensive. Call 512-892-2443 or schedule an appointment to learn whether silver diamine fluoride treatment is right for your child.
What Is Silver Diamine Fluoride?
Silver diamine fluoride, commonly called SDF, is a topical dental liquid used to help arrest active tooth decay and reduce sensitivity. It combines two important components:
- Silver: Helps control the bacteria involved in tooth decay.
- Fluoride: Helps strengthen and remineralize weakened tooth structure.
Unlike a filling or crown, SDF does not replace missing tooth structure or restore the tooth’s original shape. Instead, it may be used to stabilize a cavity and prevent it from becoming worse while Dr. Arzegar monitors the tooth or plans future care.
Silver diamine fluoride is one part of an ongoing cavity-management plan. Your child will still need routine examinations, preventive care and follow-up visits so our team can determine whether the treated area remains inactive.
Which Children May Benefit From SDF Treatment?
Silver diamine fluoride can be especially helpful when conventional treatment would be difficult to complete immediately. Dr. Reza Arzegar may consider it for children who:
- Have one or more active cavities
- Are very young or unable to remain still for restorative treatment
- Experience severe dental fear or anxiety
- Have developmental, behavioral, sensory or medical considerations
- Need extensive dental care that cannot be completed during one appointment
- Have difficulty tolerating drilling or local anesthesia
- Are waiting for hospital dentistry or another planned procedure
- Have areas of decay that are difficult to restore conventionally
- Have sensitive teeth caused by exposed dentin
- Are at high risk of developing additional cavities

Benefits of Silver Diamine Fluoride for Children
The simple application process makes SDF a valuable option for children who need help controlling decay but are not ready for more involved treatment.
Potential benefits include:
- A brief and noninvasive application
- No drilling during the SDF application itself
- No injections during the SDF application itself
- Help slowing or arresting active tooth decay
- Reduced sensitivity in affected teeth
- Additional time before restorative care when clinically appropriate
- A treatment option for children who have difficulty tolerating conventional procedures
- Support for children with multiple cavities or extensive dental needs
- Protection of weakened dentin from further breakdown
SDF does not eliminate the need for daily brushing, a cavity-conscious diet or professional dental care. Its role is to help control a specific area of decay as part of a broader treatment and prevention plan.
Will Silver Diamine Fluoride Turn the Tooth Black?
Silver diamine fluoride permanently darkens the decayed portion of a tooth when the treatment is working. Healthy enamel generally does not turn black, but the area damaged by the cavity may become dark brown or black.
This color change is the most important consideration for many parents. It may be less noticeable on a back tooth, but it can be visible when SDF is applied to a front tooth.
Before treatment, Dr. Arzegar will show you which area is expected to darken and discuss whether the appearance is acceptable. Parents or guardians must understand and consent to the expected staining before SDF is applied.
The liquid may also cause temporary staining if it contacts the lips, skin or gums. Our team takes precautions to isolate the tooth and protect the surrounding tissues during application.
Does SDF Replace a Filling or Pediatric Crown?
Silver diamine fluoride does not rebuild a damaged tooth. If a cavity has created a hole, weakened the tooth or affected its shape, your child may eventually need a restoration.
Depending on the condition of the tooth, future care may include:
- A tooth-colored dental filling
- A stainless steel or zirconia pediatric crown
- Primary tooth pulp treatment
- A tooth extraction when the tooth cannot be restored
- Continued monitoring when no additional treatment is currently needed
For some children, SDF serves as an interim treatment until they are older, more comfortable in the dental setting or able to complete restorative care. In other cases, it may remain part of the ongoing management plan for a baby tooth that is approaching its natural time to fall out.
When SDF May Not Be the Right Treatment
Although silver diamine fluoride is useful in many situations, it is not appropriate for every cavity or every child. Conventional treatment may be necessary when:
- The tooth is causing significant or persistent pain
- There are signs of infection or an abscess
- Decay has reached the dental pulp
- The tooth is too damaged to function normally
- The cavity cannot be adequately evaluated or monitored
- The tooth needs to be rebuilt to restore chewing function
- The expected dark staining is unacceptable to the family
- Your child has a relevant allergy or oral condition that prevents its use
Dr. Reza Arzegar will examine your child’s tooth and, when necessary, use digital X-rays to determine how deeply the decay extends. SDF should not be used to delay necessary treatment for a painful or infected tooth.
What to Expect During SDF Treatment
The application is generally brief and can often be completed during a routine pediatric dental visit. The process may include:
- Examining the tooth: Dr. Arzegar evaluates the cavity and confirms that SDF is an appropriate option.
- Discussing the color change: Our team explains that the decayed area will permanently darken.
- Isolating the area: The lips, cheeks and gums are protected while the tooth is kept as dry as possible.
- Applying the liquid: A small amount of SDF is placed directly on the affected tooth structure.
- Allowing it to absorb: The material remains on the tooth briefly before the area is cleaned as appropriate.
- Planning follow-up care: Dr. Arzegar explains when the tooth should be rechecked or treated again.
Your child may notice a temporary metallic taste. The treated cavity will gradually appear darker, which is an expected effect rather than a sign that the tooth is becoming worse.
Will My Child Need More Than One Application?
Some cavities require repeat applications to remain arrested. The number and timing of treatments depend on the tooth, the extent of decay, your child’s cavity risk and how the area responds.
At follow-up visits, Dr. Arzegar will examine the treated tooth. A cavity that has been successfully arrested generally becomes harder and does not continue enlarging. If the area remains soft or active, another application or a different treatment may be recommended.
Consistent follow-up is essential. SDF should not be viewed as a one-time treatment that removes the need to monitor the tooth.
Preventing Additional Cavities
Silver diamine fluoride treats selected areas of existing decay, but your child may still develop cavities elsewhere. A complete prevention plan may include:
- Brushing twice daily with fluoride toothpaste
- Helping younger children brush thoroughly
- Flossing between teeth that touch
- Limiting frequent snacks and sugary drinks
- Choosing water between meals
- Scheduling regular dental examinations and cleanings
- Receiving professional fluoride treatment when recommended
- Applying dental sealants to cavity-prone permanent molars

Comfortable Care for Anxious Children
One of the primary advantages of SDF is that it can help some children receive meaningful cavity treatment without undergoing drilling or a longer restorative appointment.
Our office is designed to help children and families feel welcome. Video games, televisions above the treatment chairs, child-friendly music and other thoughtful features can make the dental environment feel less intimidating.
If your child requires treatment that cannot be completed with SDF alone, Dr. Arzegar can discuss behavior guidance and appropriate pediatric sedation options. Recommendations are based on your child’s health, age, anxiety, developmental needs and required treatment.

Frequently Asked Questions About Silver Diamine Fluoride
What does silver diamine fluoride do?
Silver diamine fluoride is applied to an area of active tooth decay to help slow or stop the cavity from progressing. It may also reduce sensitivity in the affected tooth.
Does SDF remove a cavity?
No. SDF helps arrest the decay, but it does not remove damaged tooth structure or rebuild the tooth. A filling, crown or another procedure may still be needed to restore the tooth’s shape or function.
Will SDF turn my child’s whole tooth black?
SDF darkens the decayed tooth structure rather than healthy enamel. The amount of visible discoloration depends on the location and size of the cavity.
Is the black staining permanent?
Yes. The decayed area treated with SDF will remain dark. If appearance becomes a concern, Dr. Arzegar can discuss whether a filling, crown or another restoration may cover the area.
Is silver diamine fluoride painful?
The application is noninvasive and does not involve drilling into the tooth. Most children tolerate it well, although the liquid may have an unfamiliar taste and the surrounding tissues require careful protection.
How long does SDF treatment take?
The application itself is usually brief. The total appointment length depends on the number of teeth being evaluated, your child’s comfort and whether other preventive or diagnostic services are needed.
How many SDF treatments will my child need?
Some cavities need more than one application. Dr. Arzegar will monitor the tooth and recommend follow-up treatment based on whether the decay has become inactive.
Can SDF be used for children with special needs?
Yes, it may be helpful for children who have difficulty tolerating conventional dental procedures. Treatment is still individualized according to the child’s health, oral condition and specific dental needs.
Can my child eat after silver diamine fluoride treatment?
Our team will provide instructions based on the material used and your child’s appointment. Follow the guidance you receive before allowing your child to eat, drink or brush the treated area.
