Yes, it is completely normal for a 9-month-old baby to not have any teeth yet. The timing of teething can vary widely among babies.
Average Timeline for Teething:
Most babies begin teething between 4 to 12 months.
The first teeth to appear are typically the lower central incisors (bottom front teeth), followed by the upper central incisors.
By 12 months, many babies have 4â8 teeth, but some might not have any yet.
