PRIMARY TO PERMANENT TEETH PROGRESSION PROCESS

Primary and permanent teeth are inter-reliant units. They both interact with each other and depend upon each other. But, the relationship between the two can be changed by things like tooth decay lesions and mechanical trauma. In simpler words, if a child experiences dental trauma now, it could disturb the development of permanent teeth in about twelve to sixty-nine percent of cases. So, it is up to the parents to help their kids protect their primary teeth to have healthier permanent teeth later on.

EARLY TEETH DEVELOPMENT

By the sixth to seventh weeks of an embryo being in its mother’s womb, primary teeth development process has begun. That is, the initiation stage and dental lamina stage. By eighth to tenth weeks, the embryo’s teeth development is in the proliferation stage. This entails the bud stage at eight weeks and the cap stage at 9th to 10th weeks. The histodifferentiation process begins at the 11th week, bell stage or enamel organ formation, going up to the 12th week—dental germ formation. Calcification then happens and is also called maturation and entails a complete development of enamel and dentin. Finally, the tooth will enter its eruption stage where the root will grow.

A FURTHER DESCRIPTION OF PRIMARY TEETH

It is not several mothers who realize that their newborn infants have teeth. At birth, babies often have up to 20 primary teeth, also baby teeth, hidden in the gums. At this point they are almost totally formed and just invisible. However, as the baby grows, their teeth continue to mature so that by the time they are two and half years old, their baby teeth start to erupt. The process of eruption goes like this:

Upper jaw

  • Central Incisor teeth – They erupt at 8 to 12 months and shed by six to seven years
  • Lateral Incisor teeth – Erupt at 9 to 13 months and shed by 7 to 8 years
  • Canine or cuspid – Erupt at 16-22 years and shed by 10 to 12 years
  • First molar – Erupts at 13 to 19 months and shed by 9 to 11 years
  • Second molar – Erupts at 25 to 33 months and sheds by 10 to 12 years

Lower jaw

  • Second molar – Erupts at 13 to 31 months and sheds by 10 to 12 year
  • First molar – Erupts at 14 to 18 months and sheds by 9 to 11 years
  • Canine – Erupts at 17 to 23 months and sheds by 9 to 12 years
  • Lateral incisor – Erupts 10 to 16 months and sheds by 7 to 8 years
  • Central incisors – Erupts 6 to 10 months and sheds by 6 to 7 years

HERE IS A SUMMARY OF HOW PERMANENT TEETH ERUPT

Upper teeth

  • Central incisor – Erupts at the age of seven to eight years
  • Lateral Incisor – Erupts at the age of 8 to 9 years
  • Canine- Erupts at the age of 11 to 12 years
  • First premolar or first biscupid – Develops between ages 10 and 11 years
  • Second premolar or second biscupid – Develops between ages of 10 and 12 years
  • First molar – Develops between six and years
  • Second molar – Erupts from ages 12 to 13 years
  • Third molar or wisdom tooth – Grows from ages 17 to 21 years

Lower Jaw

  • Wisdom tooth or third molar – Develops between ages 17 to 21 years
  • Second molar – Erupts from 11 to 13 years
  • First Molar erupts from 6 to 7 years
  • Second premolar – Erupts from ages 11 to 12 years
  • First premolar – Erupts from ages 10 to 12 years
  • Canine – Erupts from ages 9 to 10 years
  • Lateral incisor – Erupts from ages 7 to 8 years
  • Central incisor – Erupts from ages 6 to 7 years

As you can see, babies’ primary teeth develop at different levels and by the time they are 3 years old, all their 20 primary teeth are out. Additionally, a child’s jaws continue to develop so as to create room for their future permanent teeth (adult teeth). These adult teeth will start to develop when a child is about six years of age or when their primary teeth will start to shed — usually at the age of six or seven years. The process will go on until a child is twelve years old.

Awesome experience with Dr. Ivanov! He shows great passion in his work, and cares about his patients and their concerns. I had my braces for 1yr 11 months and now I’m wearing my retainers. It amazes me as I look at my before and after pics of how great he is. Very happy and well pleased with my results that I referred a colleague of mine. Special thanks to Dr. Ivanov and his team for the fabulous job done!

I took my son to Dr. Ivanov because he had a severe overbite. The doctor explained everything to me with patience and understanding. I noticed the improvements in no time. I thought my son would be in braces for 3-4 years. My son, under Dr Ivanov’s care, now has the straightest most beautiful teeth (in only 2 years)!. The shape of his face adjusted to the changes as well and he looks ‘Hollywood’ Ready’. I am very satisfied with the doctor’s work. His office staff is great as well. Dr. Ivanov is very professional and I highly recommend!

Amazing experience! I’ve had my braces for 6 month now and I’m impressed of how much my teeth have changed. No pain at all. Dr. Ivanov is such a sweet person and very professional, he knows what he’s doing and always cares for patients personal concerns. Highly recommended!

Dr . Ivanov is in one word AMAZING . I been under his care for a year and I got to say What a change!!! I cannot wait to see the final results . . He always answers all my questions, in every visit he will take the time to understand how my teeth are improving and always makes the right decision. The staff is awesome, I always feel right at home . I made the best choice when I decided to get my braces with Dr . Ivanov. There’s is no doubt he is the best ortho . Thank you Dr. Ivanov for the hard work and for being so amazing and helping me feel awesome with every month visit . Anyone who is looking for a good ortho and the best care , there’s no other , Dr. Ivanov is the man!!!

Dr. Ivanov, Amy, and Helen are great! Dr. Ivanov took his time to get to know me, understand my needs, and come up with a treatment plan within my expectations. He offered various treatment options, and Amy and Helen offered payment options. They answered multiple questions without hesitation and with patience. They are all very friendly and personable. Happy I got my braces with them today. P.S. They all worked very quickly to get my braces on as painless as possible. And it went better than expected.

Dr. Ivanov was amazing. When I first got my braces I was scared it was going to last 4yrs for my teeth to look better but it only lasted 2yrs and the results are beyond amazing. I’m really happy with everything and would absolutely recommend him to anyone. Thank you so much.

Dr. Ivanov was my orthodontist. I had a very difficult case, I had an opening in my front area when I closed my mouth. Most orthodontist that I went to said that this case would be impossible to do without surgical intervention. Dr. Pavel thought outside of the box and was able to straighten my teeth WITHOUT surgical intervention. I felt that I was in safe hands because after careful research I found that he graduated at the very top of his class. He was able to do a complex braces technique called the MEAW technique to straighten my teeth. He has restored my self confidence and smile. I highly recommended Dr. Ivanov, he will go out of his way to make sure that your treatment plan is well thought out and he will spend his time to evaluate your situation. He is the Best Orthodontist in the North Miami\Aventura area.

I’ve been visiting Ivanov since December 2015. I had crossbites, crowded teeth, and just all the works. Together with his professional and amazing staff I was able to slowly over the years fix my smile into something life-changing. I am internally grateful to him as well as his staff, especially his assistant and front desk. If you don’t come here then you’re just passing up a great opportunity to change your life for the better and meeting amazing people who will help every step of the way to getting you a better smile! Thanks again, Mr Ivanov.

Very good experience. The attention was great. The doctor is very punctual and they don’t make you wait, which for my busy schedule is super important. Also, the time the doctor told me I had to wear the braces was the exact time I needed and I was very happy with the results. Definitely recommend him.

Dr. Ivanov and his staff really feels like my second family here and they’re always looking out for the best of me. When I first came into the office, my teeth were quite messed up, but now only after a year, it feels surreal that the braces could fix them so well. I see myself smiling alot more and feeling much more confident to show my teeth than to just smirk like I used to. They give you good advice on how to take care of yourself and take the extra step to make sure you do. When I come here for my checkup, I never feel awkward or uncomfortable because they’ll welcome and talk to you as a friend as well as your dentist, something I feel good about when I think about it walking out and saying “See you next month!”

Dr. Ivanov was amazing. He was very understanding and took the time to explain, every step of the process for my daughters braces. I am proud to say with great care her braces were finally removed and the end result is the beautiful smile she now has. Thank you

Usually, when a professional says that the reason they do what they do is to see the end results and how happy it makes their patients, you have to take it with a grain of salt. However, with Dr. Ivanov, he doesn't even have to tell you why he does what he does for you to know that it's out of pure kindness and enjoyment in seeing a (perfect) smile in his patients. From the very first moment I met him for a consultation for orthodontic work, I knew I was in good hands. Dr. Ivanov is one of the most humblest, kindest, and caring individuals I've ever met in the professional field and I know that I'll have that perfect smile in no time.

Ivan and his staff made my experience a smooth and convenient process. I am absolutely delighted and satisfied with the progress and how far my teeth has come. Ivan and his staff works effortlessly to ensure that my teeth are perfected beyond my expectations. If I had any other choice I would still choose Ivanov Orthodontic experts.

CARE FOR PRIMARY TEETH

Primary teeth demand good care even if they will shed at a given point. A child needs to be taught how to brush and floss their baby teeth to avoid dental caries (tooth decay). Once your child learns how to take good care of its oral health while still young, it will continue to do so once the permanent teeth erupt. Excellent oral health doesn’t only protect a child from tooth decay, but also from speech impairment. The first set of teeth holds a position in the jaw for the permanent teeth to move into later on. That’s why that special position should be well protected now to ensure that there will be no problem when a permanent tooth erupts in future. It should be kept from things that cause cavities and dental pain.

If there is an infection from a decaying primary tooth, action should be taken quickly to protect the adult tooth that will erupt from the same place. Note that permanent teeth are developing under the child’s primary teeth and as a parent, you should realize that your baby’s first teeth are prone to decay. Early childhood caries (also baby bottle tooth decay or nursing mouth syndrome) in infants and toddlers can damage teeth. When a child’s teeth are exposed to excessive sugary stuff for a long time, dental caries can occur.

You can reduce your baby’s odds of developing nursing mouth syndrome by making sure that it does not fall asleep while still sucking milk or another sugary liquid from its feeding bottle. Additionally, make sure that you don’t encourage your baby to use a pacifier by first dipping it in a sugary stuff like honey or table sugar. If the child requires a comforter in between many regular feeding sessions or when going to bed, offer it a sterilized pacifier that is provided by a child doctor (pediatrician) or a professional dentist. Moreover, wipe your kid’s gums with a wet washcloth or clean gauze after eating or drinking.

As soon as the primary teeth start to erupt, brush them with a little amount of water and a soft-bristled brush. It is also important to teach a toddler how to brush its teeth while supervising it to ensure that the job is well done. Only a pea-size amount of fluoride toothpaste is needed to clean a toddler’s teeth and since kids always experiment, they can swallow the toothpaste. So, be there to guide the baby and ensure that it does not swallow the toothpaste. Tell the kid to spit it out and then rinse their mouth with water.
