Dental Fillings in Children: What You Need to Know
A dental filling restores a child's decayed or broken tooth using composite, amalgam or glass ionomer; the child should not eat for the first 2 hours.
Clinical experience, misunderstood concepts and frequently asked questions. Notes from many years of practice.

A dental filling restores a child's decayed or broken tooth using composite, amalgam or glass ionomer; the child should not eat for the first 2 hours.

Full-mouth dental implants replace a whole arch on 4 to 8 implants carrying one fixed bridge or removable overdenture; treatment runs 3 to 12 months.

Dental implants suit adults with enough jawbone or bone that can be augmented, healthy or treatable gums and good general health; no upper age limit applies.

A dead tooth is not a lost tooth. Pooled data from 63 longitudinal studies place the success of primary root canal treatment at 68% to 85% under strict radiographic criteria, and separate reviews report high tooth survival afterwards. Symptoms to watch for and the options that remain.

Pregnancy shifts the odds in the mouth: pooled across 20 studies, 40% of pregnant women had periodontitis and 67% showed bleeding on probing, with bleeding rising steadily through the trimesters. Which dental work belongs before conception, and what fluoride does and does not do.

In a meta-analysis of 64 studies reporting on 3,509 metal-ceramic and 8,051 all-ceramic single crowns, five-year survival was 98.5 percent for monolithic lithium disilicate, 97.1 percent for metal-ceramic and 96.8 percent for monolithic zirconia. Types, longevity, and why a crown can start to smell.

Pediatric dentistry is prevention-led care from the first baby tooth to adolescence; early childhood caries affects 48 percent of preschool children.

Gum disease is partly inherited: in 117 adult twin pairs about 50% of the variance in periodontitis was genetic, while gingivitis showed no heritability.

Dental calculus, or tartar, is plaque mineralised onto the tooth. Brushing and home scraping cannot remove it; a clinician uses scalers or ultrasonic tools.
