Silver Diamine Fluoride Treatment for Children in Apex
Last updated
Silver diamine fluoride, commonly called SDF, is a minimally invasive treatment used to help stop the progression of selected cavities. Green Level Pediatric Dentistry & Orthodontics may recommend SDF when immediate restorative treatment is not appropriate or when delaying more involved care would benefit the child.
SDF does not rebuild missing tooth structure like a filling or crown. Dr. Michael Kim evaluates the cavity, tooth, symptoms, and child’s treatment needs to determine whether SDF is appropriate.
What Is Silver Diamine Fluoride?
SDF is a topical liquid containing silver and fluoride. The silver component helps control cavity-causing bacteria, while fluoride supports the hardening of weakened tooth structure.
The liquid is applied directly to an eligible cavity after the tooth has been cleaned and isolated. Treatment is brief and generally does not require drilling or local anesthesia, although the child may eventually need a filling, crown, or another restoration.
Benefits of SDF
Minimally Invasive Application
SDF can be applied directly to a cavity without removing tooth structure. This may be useful for young children, children with dental anxiety, and patients who have difficulty tolerating longer procedures.
Cavity Management
SDF can harden an active cavity and help slow or stop its progression when the lesion is appropriate for treatment.
Additional Treatment Time
In selected cases, SDF can help manage decay until a child is better able to participate in restorative care or until another planned treatment can be completed.
Did You Know…
The American Academy of Pediatric Dentistry reports that the effectiveness of a single SDF application in arresting cavities has ranged from 47% to 90%, depending on the cavity’s size, location, and tooth surface. AAPD SDF Guideline

- Individual cavity assessment: Dr. Michael Kim evaluates the cavity’s depth, location, activity, and proximity to the dental pulp before recommending SDF.
- Clear appearance counseling: Families are informed that SDF permanently darkens treated decayed tooth structure before consent is obtained.
- Continued monitoring: The team checks whether the cavity has hardened and determines whether reapplication or restorative treatment is needed.
The SDF Treatment Process
1
Evaluate the Cavity
The dentist examines the tooth and may take digital images. Teeth with pain, swelling, infection, or pulp involvement may require a different treatment.
2
Apply the SDF
The tooth is cleaned and isolated to protect the surrounding tissues. A small amount of SDF is applied directly to the affected area.
3
Reevaluate the Tooth
A follow-up examination determines whether the cavity has hardened. Additional SDF applications or a filling, crown, SMART restoration, or other treatment may be recommended.
“SDF gives us a conservative way to manage selected cavities when conventional restorative treatment may not be the best immediate option. We explain the expected dark staining clearly and continue monitoring the tooth so families understand each step of the treatment plan.”

“My kids have been going to this practice since they were toddlers, and having one doctor who understands their complete dental history and growth patterns has made such a difference. Dr. Kim treats them like they’re his own children and recommends only what’s truly necessary. The convenience of having both their regular checkups and orthodontics in one place has been a game-changer for our family.”
“What impressed me most was how honest the doctor is about treatment recommendations. He explained exactly why each step was needed and never pushed unnecessary procedures. Having someone I trust completely managing both my kids’ dental and orthodontic care gives me peace of mind. The staff is incredibly kind and patient with nervous children.”
“We switched practices specifically because we wanted someone who could handle both pediatric dentistry and orthodontics under one roof. The continuity of care is amazing, and our kids actually look forward to their appointments. The whole team treats every patient like family, and the clinical expertise is evident in every interaction.”

| SDF Treatment Outcome | Percentage | What the Research Shows |
|---|---|---|
| Highest reported arrest rate after one application | Up to 90% arrested | The AAPD reports that one-time SDF effectiveness ranged from 47% to 90%, depending on lesion size, location, and tooth surface. |
| Cavity arrest compared with other treatments or placebo | 89% greater arrest | A systematic review and meta-analysis found that SDF produced 89% greater caries arrest than other active treatments or placebo. This is a relative comparison, not an absolute arrest rate. |
| Primary-tooth cavities arrested after six months | 86% arrested | A systematic review estimated that 38% SDF arrested 86% of evaluated dentin cavities in primary teeth at six months. |
| Primary-tooth cavities arrested after 12 months | 81% arrested | The same review estimated an 81% arrest rate for dentin cavities in primary teeth at 12 months. |
| Primary-tooth cavities arrested after 24 months | 65% arrested | At 24 months, the estimated arrest rate was 65%, indicating that effectiveness may decrease over time without continued management. |
| Cavities arrested in a large U.S. clinical trial | 54% arrested | In a randomized trial involving 830 young children with severe early childhood caries, one application of 38% SDF arrested an estimated 54% of eligible lesions at six months, compared with 22.5% with placebo. |

Key Findings About SDF
SDF permanently darkens decayed tooth structure. Healthy enamel generally does not turn black, but the treated cavity typically becomes dark as it hardens.
SDF is not a tooth-colored restoration. It can help arrest decay but does not replace missing tooth structure or restore the tooth’s original appearance.
Not every cavity qualifies for SDF. Teeth with spontaneous pain, swelling, infection, pulp exposure, or extensive structural damage may require another treatment.
Repeat applications may be necessary. The dentist may recommend additional SDF based on the cavity’s activity, the child’s risk of developing decay, and the response to the first application.
SDF may be part of a staged treatment plan. A tooth treated with SDF may later receive a filling, crown, SMART restoration, or another definitive treatment.
Daily prevention remains important. Brushing with fluoride toothpaste, cleaning between teeth, reducing frequent sugar exposure, and attending preventive visits help protect treated and untreated teeth.

SDF may offer a conservative option for managing selected cavities in young children and patients who have difficulty completing conventional restorative treatment. Contact Green Level Pediatric Dentistry & Orthodontics in Apex to schedule an evaluation with Dr. Michael Kim.
Questions Apex Families Ask About SDF
What does SDF do to a cavity?
SDF helps control bacteria and harden softened tooth structure. A cavity that responds to treatment typically becomes darker and firmer, indicating that its activity may have stopped.
Will SDF turn my child’s tooth black?
SDF permanently darkens the decayed portion of the tooth. Healthy tooth structure is not expected to develop the same dark staining, although temporary staining of the gums or skin can occur if the liquid contacts those areas.
Does SDF treatment hurt?
Application is generally brief and does not require drilling or an injection. However, SDF may not be appropriate when a tooth is already painful, infected, or affected by deep decay involving the pulp.
Does SDF replace a filling or crown?
Not always. SDF arrests decay but does not replace missing tooth structure. Depending on the tooth’s condition, the child may later need a filling, crown, SMART restoration, or another treatment.
How often does SDF need to be applied?
The schedule varies according to the cavity and the child’s risk level. The dentist may recommend follow-up and reapplication because a single treatment does not arrest every cavity and its effect can decrease over time.
Is SDF approved for treating cavities in children?
In the United States, SDF is FDA-cleared for treating tooth sensitivity. Its use to arrest cavities is considered off-label, which is a legally permitted use of an approved product based on professional judgment and available evidence. The dentist reviews the benefits, limitations, and staining before treatment.
