The A 45 pill is better known as Amoxicillin. It is available in the form of a blue and pink capsule, with the standard dosage at 500 mg. Experts recommend it as the primary antibiotic for treatment of bacterial tooth infections.
It is similar to a penicillin antibiotic which works to kill the bacteria causing this infection. You need to take the amoxicillin 500 mg dosage for tooth infection after every 8 hours. This is roughly equal to taking the medicine 3 times a day.
Given that A 45 is an antibiotic, it does not help you against viral infections such as the common cold. Some minor side-effects include nausea, rashes and diarrhea.
So, if you are given a course of the A45 pill for toothache and are curious to know more, this article is the one for you!
Antibiotics are mostly used when the infection is severe, or you have a weak immune system. The type of drug needed depends on the type of bacteria responsible for the infection.

Symptoms of a Tooth Infection
The primary sign that you will encounter is pain. However, the pain is not necessarily restricted to the diseased tooth. Pain, accompanied by swelling, may extend to the face, jaw and neck.
Additional symptoms include tenderness around the affected tooth and increased sensitivity to hot or cold foods.

Amoxicillin or a45 for Tooth Pain
Experts consider this medication to be the first and safest choice. For an infection of a more severe nature, amoxicillin is given in combination with some other medicine. This allows the antibiotic course to cover a wide range on the spectrum and makes it more effective.
The drug given in conjunction with amoxicillin is Clavulanate. The amoxicillin clavulanate dosage for tooth infection varies depending on the patient.
On average, you are given the oral tablet dose as 250-500 mg after every 8 hours. Alternatively, a stronger dose is for you to take 500-875 mg after every 12 hours. You should take the drug at the same time every day.

If you miss a dose and remember it too close to the time of the next dose, then skip the missed one. These are strong medicines, so you should take care not to double dose.
Side Effects of Amoxicillin
The A 45 pill for toothache is not without its complications. The minor ones are vomiting, diarrhea and headaches.
If your diarrhea has blood in it, then stop taking the medicine and call your doctor.
If more serious problems begin to manifest, such as
- Difficulty breathing
- Stomach cramps
- Breaking out in hives
You should immediately go for emergency medical attention.
What Antibiotic Is Used for Tooth Infection?
At times, a tooth infection requires surgical intervention such as a dentist draining the pus in the abscess. Removal of the tooth is another way.
Antibiotics are mostly used when the infection is severe, or you have a weak immune system. The type of drug needed depends on the type of bacteria responsible for the infection. Make sure to consult your doctor, and please do not self-medicate if you are in pain.
Antibiotics belonging to the class of penicillin are used to treat tooth infections. These include amoxicillin and penicillin. Even though these are commonly used, many people are allergic to these medicines.
Your doctor will be sure to prescribe you a course of antibiotics while taking your medical history of any possible allergies into account.
What Is the Best Antibiotic for Gum Infection?
Although rare, a tooth infection can spread to other parts of the body. The gums are among the first parts to be affected. This condition, known as gingivitis, usually goes away after 10-14 days. The drug prescribed by doctors is known as ‘Metronidazole’ or ‘Flagyl’.

It is for patients going through a severe form of gum disease. It works best with tetracycline, a drug that decreases inflammation. Tetracycline also destroys the enzyme collagenase.
Collagenase eats away at bone and connective tissue, due to which your teeth may loosen up and eventually fall out.
Alternative Medicine: The 1174 Pill
Penicillin V Potassium is another highly effective medication. It treats a variety of conditions such as infections of the respiratory system and rheumatic fever. It is not that you can only treat tooth infections with it.
The medication works by preventing infectious bacteria from creating a protective covering around themselves inside the human body.
Normally, this protective coat would prevent bacteria from being destroyed by your immune system. Without it, the bacteria are killed.
You should not attempt to use this medicine for viral infections, like the flu. Taking antibiotics when you do not need them heightens the risk of getting an infection that is resistant to that drug.
Penicillin V Potassium is available as either a tablet or oral solution. Whatever your physician prescribes, you try to stick to that exact amount.
The 1174 pill for tooth infection dosage comes in the form of a 500 mg white tablet. You need to take it either 3 or 4 times a day, depending on the instructions given by your doctor.
The oral solution is to be put in the refrigerator (not frozen) and the tablets stored at room temperature. Any medicine that has not been used after 14 days must be carefully disposed of.
What Is the Best Pain Pill for Toothache?
Antibiotics are not available over-the-counter without a doctor’s prescription. However, in order to gain relief while you wait for treatment, you can take painkillers.
So, what is the best medication to take for tooth pain? Recommended ones are ibuprofen and naproxen since in addition to relieving pain, they also lessen the inflammation.
Will Antibiotics Stop Tooth Pain?
The job of antibiotics is not to relieve pain. They are responsible for either killing or blocking the action of infectious bacteria.

A complete round of antibiotics may cause the intensity of pain to decrease, but this is a slow and less effective way of gaining pain relief. Over-the-counter pain medicines are a better option for you.
How Long After Starting Antibiotics Will Tooth Pain Go Away?
A physician will prescribe you a course of amoxicillin that lasts between three to seven days. The symptoms begin to get much better after only 2-3 days, but keep in mind, you have to complete the full course as given by the dentist or doctor. Do not stop taking the medicine just because the symptoms alleviate.
There are dangers to leaving the antibiotic course unfinished, such as the infection remaining for longer. In contrast, you may develop a new infection, this time with bacteria that are resistant to the medication you were previously taking.
Bottom Line
Bacterial infections of any kind, especially in the teeth and gums, are extremely painful. You want to go for instant pain relief in addition to treating the disease itself.
The best antibiotic is the a45 pill for toothache, as is acknowledged world-wide. Thankfully, the side effects reported are also minor. Instead of being used singularly, you should take it in conjunction with other medicines to reduce pain and inflammation.
Your doctor will prescribe you a proper course depending on your medical history. Do not attempt to start or stop this medicine without a consultation.
