Cavities and toothaches can make even the happiest kids feel down. We can help turn those frowns upside-down with gentle treatment options like silver diamine fluoride.
Silver diamine fluoride, or SDF, is a liquid that is brushed onto a decayed tooth to stop the decay from progressing. The silver acts on the bacteria driving the cavity; the fluoride strengthens what is left of the tooth structure. There is no drilling, no needle and no numbing, and the application takes about a minute per tooth.
It is not a replacement for every filling, and we will not present it as one. SDF arrests decay; it does not rebuild the missing part of the tooth. What it does extremely well is buy time and avoid trauma — which for the right child is worth a great deal.
SDF is often the better choice for very young children who cannot yet cope with a restoration; for children with dental anxiety or sensory sensitivities for whom the drill is the real obstacle; for children with special healthcare needs where a conventional appointment would require sedation; for a baby tooth that is going to fall out before the decay would ever threaten it; and for stabilising several cavities quickly while a longer treatment plan is worked through. It is also useful for decay in spots that are physically hard to restore well in a small mouth.
SDF permanently darkens the decayed area it treats, usually to black. Healthy enamel around it is unaffected, but the treated spot stays dark until that part of the tooth is restored or the tooth is lost. On a back molar nobody will ever see it. On a front tooth, parents often mind, and they are entitled to. We show you where the staining will be before we apply anything, and if the appearance is not acceptable to you, we will talk about the alternatives instead. Any product or website that presents SDF without mentioning the stain is not giving you the full picture.
The tooth is dried, the surrounding tissue is protected, and the liquid is applied with a small brush and left to absorb for a minute or two. Most children find the taste briefly metallic and that is the extent of the complaint. There is no recovery period — your child eats and drinks normally, and goes back to school the same morning. SDF is usually reapplied at intervals your dentist recommends, because arrested decay still needs monitoring at regular exams.
Stopping decay is not the same as being done. A tooth treated with SDF is checked at every visit to confirm the decay has actually arrested, and many teeth are eventually restored properly with a filling or a crown once your child is old enough to manage it comfortably. Prevention carries on alongside: sealants on vulnerable back teeth, fluoride varnish, and the brushing and snacking habits that decide whether new cavities appear at all.
51% of kids between the ages of 5-11 have at least one cavity. If left untreated, cavities can lead to further complications like tooth infections.

Complimentary second opinion
Bring an outside treatment plan
We understand that you want to understand all of your child’s options before proceeding. That’s why we are happy to extend complimentary second opinions. If you’ve recently gotten a treatment plan from another office that you’re not sure of, feel free to bring it by!

SDF is brushed on in about a minute per tooth with no drilling and no injection — often the difference between treatment happening and being postponed.
Several cavities can be stabilised in a single short visit while a longer treatment plan is worked out at your child's pace.
For very young children, anxious children and children with special healthcare needs, SDF can achieve control without a longer, more involved appointment.
Your pediatric dentist confirms SDF is appropriate for the tooth and shows you exactly where the permanent dark staining will be before anything is applied.
The tooth is dried, tissue is protected and the liquid is brushed on and left to absorb — about a minute, with no numbing needed.
We check the treated tooth at each exam to confirm the decay has arrested, reapply as recommended, and restore the tooth properly when your child is ready.
Yes — the decayed area it treats darkens permanently, usually to black, and stays that way until the tooth is restored or lost. Surrounding healthy enamel is not affected. On back teeth it is invisible in daily life; on front teeth it is noticeable, and we will show you where it will be beforehand so you can decide. If the appearance is not acceptable, say so and we will discuss alternatives.
Sometimes, and sometimes not. SDF stops decay from progressing but it does not rebuild the missing tooth structure, so some teeth are eventually restored with a filling or crown once your child can manage the appointment comfortably. For a baby tooth close to falling out, SDF is often all that is ever needed.
There is no drilling, no injection and no numbing, and children generally report nothing worse than a brief metallic taste. Your dentist reviews your child's history first — including any silver allergy — and will tell you if SDF is not suitable. Eating and drinking go back to normal straight away.
That depends on the tooth and on your child's decay risk; your dentist will give you an interval and check the treated surfaces at every exam to confirm the decay has genuinely arrested. It is a treatment that gets monitored, not one you can apply and forget.
