Much of the natural formation and placement of teeth happens by the time a person reaches their teen years. We present here the normal tooth eruption timeline, which outlines when teeth appear and fall away, and helps you identify molars by age or order of appearance. As you’ll learn below, your teeth develop in two stages. We also focus on the question “When do molars come in for adults?” and the effects if they don’t fully erupt — especially the latter one. The extent to which these permanent teeth erupt can determine the presence of future dental problems and the need for a dentist to address them.
What Are Baby Molars?
Generally, twenty baby – otherwise known as primary – teeth are developed by birth. By two and a half to three years, these baby teeth emerge from the jawbones. The baby teeth carry a smaller size and whiter appearance than the permanent teeth that settle into the mouth by early adulthood.
Tooth eruption commences with the lower central incisor appearing between six to ten months. Incisors help you take food bites. At eight to 12 months, the upper central incisor erupts. The remaining baby teeth follow during a 9 to 33-month window.
Among these primary teeth are the baby molars. A person’s molars occupy the back of the mouth. The functions of baby molars consist of chewing and grinding.
When Do Baby Molars Come out?
The first four molars are not the ones that will go with you into adulthood. Specifically, they shed as follows:
- Age 9 to 11 years for the upper and lower first molars
- Age 10 to 12 years for the upper and lower second molars
- By age 12, all of the baby teeth will have shed
During this period of transition, proper dental care can lessen the chances that the primary ones will come out and be lost prematurely. Below, we’ll explain what can happen when the baby teeth are lost too early. Good habits for the children include brushing, flossing, eating healthy foods, avoiding candy and sugary drinks, and paying regular visits to the dentist.
When Do Molars Come in for Adults?
Children as young as six years old begin to have permanent teeth erupting. This means that you were getting new permanent teeth as you said good riddance to the baby ones. The phenomenon of teeth becoming loose in childhood results from the emergence of the permanent teeth. As you’ll read below, the time when your baby teeth were shed and when the permanent ones appeared plays a role in future dental conditions.
The quartet of third molars, often called the “wisdom teeth,” constitute the last of the thirty-two permanent teeth. If your mouth is typical, the remaining 28 permanent teeth will push through the gums by your 13th birthday.
Between the ages of 17 and 21 usually answers the question “When do molars come in for adults?” when it comes to wisdom teeth. As with the predecessor molars that you shed, the wisdom teeth reside in the rear of the mouth. Since your mouth has developed with other permanent teeth, your wisdom teeth do not chew, grind, or otherwise help you eat food. In fact, dentists may recommend removal of these teeth as a preemptive measure against complications and diseases that may arise from having wisdom teeth not properly erupt.
What Happens if Your Last Molars Don’t Fully Erupt?
When your wisdom teeth do not fully push through the gums, you have impacted wisdom teeth. This normally happens because your mouth lacks enough room for the third molars to fully erupt. Your mouth may become too crowded if you lost your baby teeth too early and permanent teeth fill that void. Such a deviation from the typical tooth eruption timeline can keep the third molars partly inside the gums.
Impacted teeth can be painless, but they are often painful. Either way, wisdom teeth that don’t fully erupt create potential oral health hazards. These teeth are harder to brush, floss, and keep free of sugar and other particles. The interaction of bacteria and food builds plaque and causes an inflammation of the gums. This condition, known as gingivitis, marks the onset of pericoronitis.
Pain and swelling in your jaw represent two signs of impacted teeth. Other symptoms of having molars that don’t fully erupt include:
- Bleeding, tenderness, redness, or swelling in the gums
- Foul taste or smell in the mouth
- Mouth does not open without pain, discomfort, or other difficulties
What Treatments Are Available if the Last Molars Don’t Fully Erupt?
Wisdom teeth extraction is the primary way to handle a permanent molar that does not fully erupt. The oral surgeon numbs the area with local anesthesia or other methods, and then pulls the teeth out. This also impacts on the jaw. Some discomfort and pain normally follow, but the irritation normally does not last beyond a few days.
The dental community has not reached a consensus on whether to remove impacted teeth if the patients do not experience symptoms. Those who adopt an approach of waiting for effects contend that the discomfort and inconvenience to the patient outweigh the benefits. Dentists in the pro-removal camp seek to get the patient ahead of the potential infections, cysts, and damage to other teeth that might result from impacted wisdom teeth.
Can You Prevent Partial Eruption?
You or your children won’t find a sure way to ensure full eruption of the teeth. Instead, the focus of any preventative measures turns to reducing the risks and impacts of not having the molars fully erupt.
Injury or trauma to the mouth can increase the chances that the molars won’t fully appear. Athletes should wear mouth guards. These protectors normally go on the upper teeth. Those with braces or other dental appliances might need guards for the lower teeth.
Taking care of teeth helps defend against the infections that come with partially erupted teeth. Brushing twice per day, flossing regularly (especially after the last meal of the day), and dental visits at least twice per year make your teeth less conducive to infection. Also, x-rays taken by your child’s or your dentist might catch a partially erupted tooth and suggest options for removal of the wisdom teeth.
Conclusion
The answer to “When do molars come in for adults?” is an important part of understanding when and how your teeth erupt. More importantly, you need to be aware that your molars may not fully erupt or may try to come in crooked. If this happens, you face an important decision on whether you should have them extracted before they generate infections or oral diseases.
